Pretty interesting game, the pixel art for the level gives me a lot of nostalgia to the Balloon Tower Defense games and I like that a lot. I also appreciate the multiple enemies and towers! I will say this though, the challenge was very noticeable in the beginning and I had a lot of fun with that, but then as it progressed it felt extremely easy unfortunately. The only reason I got to wave 45 was because I was so curious what were the mysterious towers were and how would everything look and shoot once completely upgraded. And my curiosity was rewarded as the hidden towers and final upgrades were pretty nice! Overall great game for the jam!
