Neat idea. I liked the zoom out effect and the use of the particles for the vortex. The highest score I got was 20. I found that I didn't need to use CTRL to progress. Space was enough. I recommend changing the enter key to 'Space' so its easier to jump back into the game.

liked it!

A very mesmerizing experience! (I actually feel a bit dizzy now after playing around 10 runs, can't imagine how you must've felt during development ^^)
The main mechanic works quite well and seems decently balanced. But as mentioned before, it somehow felt wrong to jump backwards, and I believe I couldn't have made it work anyway since everything happens so fast. My highscore was 26 and I feel like the game could be just a tiny bit more forgiving when jumping over. Btw: Is it possible to actually escape? :)
I really like the simple but effective visuals, especially the sympathetic character. Some music and sounds would've been awesome and could've transformed this game into even more of a trip.
Overall, a very nice first entry for you, hope to see you around again next time! :)

@rschoellgen Thanks for your feedback! I'll think about removing CTRL to make it a 1-button game, it really doesn't have much of a purpose. I didn't want to use Space for restart to prevent accidentally skipping the game over screen, but I'll take a look at it.

Hey @erkberg thanks for playing! Yes I definitely want to add music and polish a bit more, and maybe wrong jumps just lead to a time penalty, we'll see. Glad you liked it so far!
PS: and no, actually you can't escape :/
