Really fun little tower defense-like game! The core mechanic feels fresh (maybe even original?) and the visuals look nice.
It took me a while to realize you can actually move around the map — a tiny hint there would help a lot. Also, in the tutorial I found myself wanting to click on stuff — a bit of interactivity there could be cool.
Also spotted a small visual bug on the Game Over screen: the high score text is kinda squished and shoved way off to the right.
Cool concept overall, looking forward to seeing where you take it!
