You're my first full 5 star rating! A really good mix of platformer with puzzling elements (which usually dont go well together; but i felt you had the mix right with it mostly being a challenging platformer with just a hint of puzzle in terms of figuring out what path to take to get the first keys so you wont interrupt yourself on the later runs).
Was quite challenging; I'll admit that I have a low frustration threshold so I eventually got a bit frustrated with not being able to do one of the levels and gave up, but I'm not holding that against the game since its the style of game. I think maybe one more easy level at the start would have been appreciated, i think i had to do the 2nd level like 10 times to get it hahaha (maybe that's just my incompetence), but then the following levels weren't quite as hard I felt.
Things I liked:
>Great idea for a game
>The mechanics of the game were simple but utilised well
>Art style worked well for the game I thought
>Audio was great; I was bopping along to the music from the start
>Fit the theme very nicely with a unique and innovative game loop
Things to improve:
>A restart button would be nice (sometimes I knew I had immediately stuffed a run up, but I had to wait for the time to run out to restart, when I just wanted to get back to playing straight away)
>A bar to show the dash filling up again would be nice, so I knew when I would be able to dash again; I found it a little frustrating when I would push the dash button JUST before it was ready again, and hence stuff up my run.
>Maybe make the 2nd level easier? I found the 3rd and 4th easier than it because there was less chance to run into yourself; but maybe I just did the 2nd level poorly.
Well done! I hope I find more games like this in the jam!
