It's fine 😅 Making a game in such little time can be stressful, and I couldn't make a game like this! Heck, I've only ever made scratch games, so you not perfectly optimizing this game is fine. If you know how to optimize this better, update it in the future once voting is over.
found a bug! if you grab a animal from the shop and then reroll, you'll keep the animal even if you don't have enough! and then you can buy it and go into debt.
