This is one of my jam favorites so far!
It looks really cool and fits perfectly in the 64x64 resolution. I like the idea and the realization. The music is consistent. Everything feels pretty polished like if the game would be in a late development phase. The Tutorial could be a lil quicker. But Tutorials aren't that easy, especially in 64x64 pixels ;)
At first I ran into a problem. I couldn't use the scroll wheel cause my browser (Chromium Edge) was still scrolling the entire page. But I figured out when I hold CTRL while scrolling (like you do to zoom in and out on websites) it worked just in the game.
