Congrats on completing the jam! I thought it was fun and just the right scope for a jam game. If you were to expand it, it would be cool to include new spells to purchase and further upgrades. More enemy variations, or a larger level with multiple platforms would be awesome too. It would have a very Risk of Rain feel to it then.
I did notice that the difficulty seemed to stop growing after a point, and my character was so powerful that nothing could touch them. One minor issue I ran into is that upgrading acrobatics was actually detrimental - Instead of the bees flying at the top of my jumping arc, I had to time my shots to take them down.
