It's a fun game and pretty polished than I expected out of a $10 indie game.

Gunplay is fun and satisfying.
Good music
Customizing the mech is nice

A lot of the difficulty came from the scarcity of healing. I know you're supposed to push for the meta upgrades to aide this, but doing it so rigidly from very early on in the game feels off. It felt too punishing too soon and didn't make me want to keep going and trying again. Especially since the early pacing is really easy.
