Pretty good game actually! But it got a bit frustrating relatively quickly as a puzzle game. I'll explain below:
Good things first:
You've nailed the presentation well I'll give you that. Especially as you've made your art and sound everything on your own, good on that! The simplistic, but well polished art carries alot!
The platforming is smooth and easy to control! Well done! I find myself thinking more about the puzzle rather than fiddling with the controls itself, which is something you want to focus on.
Caveats:
I wished you would allow the moving lasers to stop moving (and tell the player which direction its turning) before the player moves. This can let the player first absorb the situation. I never got past level 12 simply because the of that.
The death sound FX is loud, obnoxious and get annoying fast. And given that the level auto restarts, it gets stale VERY quickly.
From a design point of view, I would suggest that you allow the player to see both the superposed particle on each screen so it's easy to compare and contrast the distance between them. This is important for the earlier levels where you have to fine tune their distance before entering the portals.
I hope I don't sound like I'm bashing the game, but I actually REALLY like this game. The caveats I've point are the last remaining pieces that prevent me from fully enjoying the game.
Once again, this is a great game!
