This is a pretty neat spin on the tower defense idea, Difficulty ramps up quite high for wave 3, However, I really enjoyed the direction this game is going. I wish you had more time and could add more visual indicators (health of wall, upgrades etc.) and this would be a really neat game that I wouldn't mind throwing a few dollars to pick up on steam or itch if fleshed out further. Great job with the game and submitting for this Jam. nice work
