Love to hear the feedback that the game has potential, I had fun making it and want to keep working on it.
Agreed that those are the weakest parts of the game. I did not get the chance to iterate on the late game difficulty ramp the way I wanted, and the audio needs to be reworked.
On the difficulty thing, I definitely need to playtest and tune the numbers more, but I also have some ideas and features that I didn't have time to implement during the jam that might help out with that. Thanks for helping me confirm that thats an important thing to focus on!
