Really fun game. I went entirely without the shop upgrades. Purely interest maxxing, compounding interest investments in my shop and then made fish tastiness scale with interest.
If you ever go back and add onto the game, logging and displaying your balance graphically throughout the run would be really fun at the end as a reward. That, and an endless mode would be the only things I'd add. Super simple, fun gameplay and really charming art! 
Thats awesome! I would definitely love to have put a graph of some sort in at the end haha, thank you for playing :)
Adding another comment as I came back to play the game again. So happy to see a stat screen with a graph!!!! Seriously awesome the game is peak now. Also I broke the game in a completely different way than previously by recursively spawing bees and angry kitties from bees and angry kitties and grinded money in a single wave until I had all shop upgrades maxed out (like reached their max price). Then, on one of the following waves, feeding cats right as they spawned on the left hand side of the screen somehow bricked the spawning system and I got no more customers anymore, the wave wouldn't end, and the only way to get out was shooting myself into bankrupcy. 10/10, incredible game. (Attatched is screenshot of game while no customers were spawning anymore.)
