Game play was easy to grasp, but I after level 3 it just kept restarting, which probably means that all there is so far? Voice acting was nice, and the running mechanic felt good as well. I'd just work on the adding a bit more variety to the levels, and maybe making the buttons look more like buttons (instead of exactly like the shard which you need to collect).

Also, I recommend uploading as a zip file, and mark as a windows download on the game page. That way you'll be able to play it in the itch app.
