This is actually nice, it's another hidden gem in the jam, and it's sad to see not many people played this. The idea is quite unique, and although the "message" is slightly questionable (no, I don't care as long as the game is fun), the setting of the game really makes for an interesting dynamic and fun gameplay. The graphics look really nice, though I really doubt if the shader is ever needed in the first place, it seems like it should also look nice without it. Also, classical music in a jam? That's new XD
For some criticisms, I think the game is really short, and it's a bit too short. I've barely even started to understand the game and it's already ended. Consider adding a few more levels to the game. I also think the robot doesn't really seem damaged despite the damage indicator implies. It would be cool if the robot were physically disabled once a certain damage threshold is met.
Anyway, this is a really well-made and polished game! Keep up the good work!
