feedback :
- add a way too reset progression in-game instead of needing to find the save folder and manually delete it
- post-end content, let us continue playing after beating the game (or implement a reset system like in every other incremental game, that let you start over with some sort of starting bonuses)
- make unlocking (not upgrading) new skills more interactive and less luck dependent, some of them are clearly more overpowered than others, and as of now, the best strategy is to wait for one of the better ones to unlock before leveling at all, this is unfun, and a good game shouldn't encourage unfun behavior from the players.
