It's a decent prototype/POC. My main criticism would be the speed of movement, which is extremely slow, even after the upgrade. Also, the text/ fonts need to be fixed, as texts are very hard to read because the spaces between words are terribly small—sometimes almost as small as the space between two letters in a word (as can be seen in one of the images on Itch page, where the text looks like "press e t o pra y").
