## 2025-03-23 - Game Key Scrolling
**Learning:** Browsers natively scroll the page when users press Space or Arrow keys. When building a web-based game, this creates a frustrating UX where the game viewport jumps around while playing.
**Action:** Always call `e.preventDefault()` on keydown events for typical game controls ("Space", "ArrowUp", etc.) when the focus is on a game container or the body.

## 2025-10-26 - Visible Instructions for Custom Key Bindings
**Learning:** When building interactive HTML5 widgets or games with custom keyboard event bindings (like "Space" or "ArrowUp" to jump), it's crucial to explicitly inform users of the expected controls. Users might not naturally assume standard keys and could get confused if controls aren't standard or visible.
**Action:** Always provide explicit, visible instructional text alongside interactive elements or games so users know the required inputs.
