Terribly fun. Reminds me of those simulations with thousands of Marios running the Mario maker levels. Or like reverse lemmings. I massively applaud you managing to code that many enemies running across the screen with minimal AI and still making it performant. I got a little slowdown around level 20 but that's not too bad. The UI is lovely and the assets are clean and cute. I loved the chunky sound design. More hero types or the ability to sell blocks is all I could see improving or a bigger level over time. I dug this game a lot and I feel like it's got some legs.
