So I like the game setup you had and the levels.  A simple fun game as you run from the portal while avoiding the obstacles. Very interesting. My only feedback is well I feel that it would have been better to have the up arrow be the jump instead of spacebar just having to think about pressing z then spacebar and then arrow got confusing so i think maybe next time for something like this make the up arrow be the jump. Just my opinion. Great job.

Argh if only the jump button worked consistently... this seems like a really fun platformer and I always LOVE having a jump-dash in the controls. I'd be interested to see further developments down the line!

Amazing controls, very intuitive game design, great music,  lovely artwork.

Overall : 10/10.

I was just about to comment that some jumps are impossible, but then I saw the extra dash key :-)

Nicely done. Very nice music, in game, for the menu I have found it a little hectic.

Figured out the dash mechanic after a bit - it kept me coming back for round after round of spike-based punishment. Love the 8-bit music!

Good job with the game. I enjoyed what I could, but the buttons were not very responsive, so that made things difficult. Looks like other comments mention the same thing. Hopefully you can get the fixed up.

Seems to have an issue with spacebar not always working when you want it to but other than that good job.

killer music and great effects on the portal, my spacebar didn't always work though oddly enough ._.

Great job, fun to play.

But the camera made me a little sick.

Good luck!
