I will definitly play this game again and this is very rare for a game jam, I really want to grind these leader board (hopefully I can do that on my phone). It reminded me of Death Spiral but the upgrades are a lot more creative and the risk reward of waiting to get more money is very very clever.
The presentation may be the best of the jam the pixel art is beautifull and there is a lot of nice thing for game feel (the little pause when hitting). Loved the background with the abilities scrolling as well as the intro.
I can't really find any other problem than the fact that it takes a while to get to the point when there is a lot of things to click at once.
It is a full game already imo
