Heya, I was assigned to give feedback to your game! After playing it I have to say that I'm quite happy with it. The sound effects were a much needed addition. Overall the polish of the game is very much on point.
I'm aware you're adding more levels, could I possibly suggest that you add incrementally sized maps? The current one is a little too big to be the starting map.
The main level and main menu could also use some music to it, as right now the sound effects help but the game still feels a little dry. Unless I'm missing something as I did see a music volume slider in the main menu Settings. Overall you should be real proud of the game that you've made! :)
