About This Game

This project is my answer to the question:
“Is it really possible to make a game for free using Gemini CLI?”

It was built with Pyxel, even though I had never used the language before.

We’ve now reached a point where anyone can create simple, playable sample games for free — and this game is proof of that.

Update - December 22, 2026 (Japan Time)
 ・Graphics improvement: 
   Changed screen rendering to 60fps.
 ・Auto-bomb added: 
   Activates when hit while bombs remain, consuming one bomb.
   Damage dealt to enemies is half that of Space Bomber.
 ・Minor adjustments: 
   Fine-tuned gameplay elements that felt off, weapon attack power, and enemy movement patterns.
Previous update
