Very cool idea, I did have to end up experimenting a lot and staring at the stats while I upgraded just to figure out what did what, but I really like the idea of taking parts and modifying yourself using them.
It was a very nice touch where your body changed depending on what stat you decided to level up, it really drives home that feeling of modding your robot in a specific way.
I think at a base you got a really fun game, obviously could have used some sound but there's something here for sure.
Only other feedback I have is that I wasn't a fan of how slow I was, so I pumped everything into speed and it didn't feel like it made much of a difference unlike something like dmg where it was clear I started 1 shotting things.
I enjoyed it enough to finish it either way, good work.
