Fun, although I'll second Jootdev on the balance being off in places. Particularly in pens 5 to 8, there were times I had my top tier maxed out but still had to wait for a minute to farm coins. I've seen paid games do worse, though.
The grammar is also off in many places - I'm guessing English isn't your native language? It didn't really detract from the experience, just an observation.
Probably the most fun game in the jam, from what I've played so far.
