The gameplay is experimental. You control a “gradius” shield with left-right and A (No up-down since A is for thrusters and gravity takes care of down.).

Changes:

* Guess what? (Coded for 7 hours! but brain feels like a mush)
* Added bosses (4 of them)
* Added more music and sfx
* Explosions
* Finalized gameplay
* Bug fix here and there
