The concept of the character getting weaker over time is really cool, but I think it would shine even more with a solid narrative behind it. Obviously, given the jam's timeframe, doing all of that would've been impossible, but the core concept remains interesting for that kind of project.
I managed to win on my first run, but I want to try out different choices to see if I can still beat it, especially since some options felt way stronger than others. My only real complaint is that the enemies are always the same without any variants, which is a bit of a shame.
Still, I had a lot of fun! You should consider developing a deeper game around this idea!
