This game is fantastic. Extremely impressive in such a short time. I don't usually play these types of games, but I found the gameplay loop very fun. The aesthetic is nice and simple, and the music fits well without being overbearing. Damage upgrades seem kinda pointless, as the enemies seem to scale much faster than the players damage anyway. It's hard to get close to enemies when the spiky ones are constantly charging at me, making me just run around in a circle until things just randomly die. The towers are fine but I think they have just a little too much health. Finally, the hitstop effect is too much. I've never been a fan of it in games, I can tolerate a frame or 2 per-hit, not per-enemy. Despite the issues, I think this game is amazing. I really hope this becomes a full game. Great job!
