The style of this game is really well done — I love how everything clearly follows the same aesthetic.
I think it’s super cool that using the same color deals double damage. I got pretty far… until the boss showed up and one-shotted me… haha… oof. But it’s super addictive!
The music and sound effects also fit really well.
My only feedback would be to maybe offer upgrades more frequently — at some point I had so many enemies that a single shot didn’t do much anymore.
