Great game! Simple and fun. Sword animation seems very slow, but the camera shake really sells the impact when you hit an enemy, such a small but important detail. I loved it!
I only had an issue with the upgrade selection, I wish the buttons had a delay (maybe activate after a second?) because I was clicking to attack an enemy when the wave ended abruptly and I accidentally clicked the longer sword. I wasn't even able to read what the other upgrade was.
In the end, I couldn't protect the pumpkin. Great work!
