Really love the art, especially the deer! The enemy variety is quite nice for a 4-day jam, and you have various spells too! I really enjoyed the freeze attack since it gave me more opportunities to move around and dodge. Overall, I think the attack rate could be increased. Most attacks taking around 4 seconds before firing is quite long, especially when you only have 2 spells. And enemy health is pretty high so it's a lot of running in circles. I think just having more action happening would really help the game feel and satisfaction to the upgrades!
Overall, fun game and really cute art! Congrats!
