Really fun! I kind of wanted to do the upgrading myself, but the gameplay was really engaging, the arena's layout made it really nice. I also think the audio worked really well. Good job!
Thanks for the feedback! I had to think of a way to upgrade the weapons, and being that type of game, I thought the best way to do it would be upgrading at each wave, but yeah I guess it would've been more satisfying to let the player upgrade the weapon
