Art was made using Aseprite, logo with Krita (using the Beon font), I'm quite used to designing art for tilemaps by now. Sound effects for stars and cubes were downloaded from freesound.org, level end was made with jsfxr. I used VCV Rack for the music loop, you can notice it's very similar to another game I made for a jam - I reused the file, changed the rythm and the notes :)
Overall I wish I had spent more time on the art, especially the main "character", oh well! glad you liked it :)
