Source and license
Asteroid Blitz is a Playnesta build based on the MIT-licensed HTML5-Asteroids by Doug McInnes (commit 930301cbda83ed3b120f64b801d937d077ee2da0): the original canvas engine, sprite/matrix math, asteroid splitting, UFO and scoring logic are retained; Playnesta additions are the page shell, viewport/meta, HUD, analytics bridge (game_load/game_start/game_restart/game_60s/game_win), touch/mouse controls, best-score persistence, and the rename from Asteroids to Asteroid Blitz to avoid the Asteroids registered trademark (Atari). The vector typeface (vector_battle_regular) ships under its original license. No bitmap, audio asset beyond the two upstream wav files, or network asset is added. Playnesta Games is the host and publisher of this web build. https://github.com/dmcinnes/HTML5-Asteroids · MIT
