Thank you! Glad you enjoyed our game.
Thank you for the detailed feedback. In the original design the were more upgrades and the waves have many more and harder to destroy meteorites. Unfortunately due to time restrictions (started working on the game late in the jam timeframe) they were cut from the final game.
Similar thing happened with the art since the player's vehicle. The current art is the original design before any buildings were created and I was in the process to redraw it but run out of time.
