OUR GOAL: LEARN HOW NATURE WORKS THROUGH PLAY
WebTug invites you to experiment first, then understand what happened. Six separate web-function games turn impact absorption, elastic preload, net interception, sticky-line timing, spring release, and dragline control into playable challenges. Each one offers immediate feedback, a plain-language explanation, a primary research link, and an explicit boundary between game rules and real biology.
The familiar character style connects the collection; the controls and physics give each challenge its own identity. These games use classic arcade ideas such as catching, launching, timing, lane defense, and landing, with original code, names, artwork, and courses. They do not reproduce another game’s branding, characters, or levels. The original WebTug Classic keeps its existing rules, and the new science arcade lives alongside it. Scores are motivation and feedback—not a validated test of learning.
Beyond the Web begins with River Shelter, a caddisfly construction challenge about underwater silk. The wider theme is the physics of materials animals make. Each release connects an original game to a short sourced lesson and a comparison activity. Silk, adhesive slime, and attachment threads are different materials; a shared visual style does not make their biology interchangeable.
WHY I BUILT WEBTUG
I wanted a browser game that could be understood before a phone screen dimmed: hold to gain lift, release to fall. The interesting part would not be discovering buttons; it would be learning how momentum carries one choice into the next opening. A spider made the rule feel physical because a visible strand could explain the held state without adding a meter.
The first playable version proved that the control was readable, but it also exposed the main design problem. Completely random vertical openings can ask for a direction change the movement model cannot deliver. That led to a generator that still surprises the player while respecting an explicit center-to-center limit.
WHY IT BECAME AN EDUCATIONAL FIELD GUIDE
Real spider silk is much more interesting than WebTug Classic’s fixed lift rule. Orb webs distribute impact, triangle weavers preload elastic structures, net-casters move a capture mesh, bolas spiders use a sticky mass on a line, widow gumfoot systems redirect walking prey, and jumping spiders use draglines for control. I expanded WebTug so Classic could open the door to those ideas without pretending that its arcade acceleration reproduces them.
The field guide now separates three layers: sourced facts about spiders and silk, simplified equations used only for teaching, and the exact first-party constants used by Classic. Species selection in Classic changes shape and released-web animation; it never changes weight, hitbox, movement, eyes, or scoring.
WHAT IS ORIGINAL IN THE PROJECT
WebTug’s game loop, physics values, path generator, scoring and medal rules, challenge-link behavior, canvas forest, spider drawing, interface, sound sequence, written explanations, diagrams, and tutorial recording were made for this project. It does not reuse a purchased game template or copy the level map of another title.
The square-eyed spider deliberately sits between pixel-art character and smooth canvas world. Tree openings use strong green shapes and pale caps so collision boundaries remain legible over villages, clouds, leaves, and score effects.
HOW I TEST A CHANGE
- Isolate the rule. Movement and gap selection live in small helpers or explicit constants where a result can be calculated.
- Test invariants. Generator tests verify arena bounds, maximum changes, and repeated-direction constraints.
- Stress a seeded sequence. The current fairness report records 20,000 portrait transitions and publishes both results and limitations.
- Play real layouts. I run narrow portrait, wider mobile, and desktop views with touch, mouse, Spacebar, and Arrow Up.
- Check the surrounding site. Gameplay stays ad-free; captions, transcript, legal pages, sitemap, robots behavior, canonical URLs, and error routes are verified with the build.
HOW SCIENCE SOURCES ARE SELECTED
I begin with primary research, official species records, university or museum references, and government publications. A taxonomy or distribution source is not treated as evidence for mechanics unless it actually addresses that behavior. Numerical comparisons include the measured material and benchmark so they are not presented as universal values.
I am the project’s creator and editor, not a professional arachnologist or materials scientist, and WebTug is not peer review. Every scientific section links its evidence so readers can inspect the original source. Simplifications and model boundaries are stated beside the equations they limit.
PHOTOGRAPHS, ILLUSTRATIONS, AND FILMS
Field photographs appear beside the explanatory illustrations so readers can compare the simplified drawing with a recorded animal or silk structure. Each photograph has its own scientific name, photographer credit, Creative Commons license, and original source link. Resizing preserves the complete composition; a source photograph assembled by focus stacking is labeled. Photographs of additional species are identified separately from the six game profiles.
The selected films remain on their publishers’ YouTube channels. WebTug embeds them with an on-demand player and adds observation questions and written visual summaries. A film is useful evidence of visible behavior, but an edited speed or apparent thread thickness is not a measurement. When the film shows a related species, the label says so. Photograph reuse licenses do not grant permission to download or republish those videos.
The watching guide connects the films to the relevant articles. The privacy page explains what happens when a player is loaded. Photo licenses, source identities, and video embedding metadata were checked on September 6, 2026.
CORRECTIONS AND UPDATE POLICY
Factual corrections are made when a stronger source, clearer wording, or implementation change is identified. The visible publication date remains the original publication date; later work is recorded separately as an update. The sitemap and structured article data use the same distinction.
Corrections can be sent to support@webtug.com with the page, disputed wording, and a source that supports the correction. The earlier systematic science review was completed on August 28, 2026. A focused editorial review on September 7 checked the six silk-mechanism summaries against their linked research, clarified which findings apply to a strategy rather than a particular character species, reviewed the six profile photograph captions and the illustration boundaries, and checked the new caddisfly lesson and comparison activities. This was source checking by the creator/editor, not specialist peer review.
On September 8, the Physics Lab’s control responses were corrected and tested across their full ranges. Its spring and pendulum motion now follows simplified force calculations; net casting combines guided reach and elastic settling. The relative settings remain teaching choices, not measured biological values.
