I actually quite enjoyed the game. It wasn't overly difficult, which in some aspects is good for the amateur gamer, but it would have been nice of there was some more thought to it. Most of the levels are just duck and run, no real puzzle solving. It doesn't take much thinking to avoid lasers and spikes. Although, of course, I also do not know if you wanted the puzzle aspect, but it would have been a nice challenge.
My only real complaint though is the portals. Especially in levels where there are lots or portals I never know I'm going to end up. It's just like a guessing game. It was kind of infuriating in some levels I kept dying because I didn't know where I was gonna go next. My suggestion is color coding. Make similar portals the same color, that way people can look and plan to see what keys they should press next.
Graphics are solid, I have no complaints. The music is fun and catchy, and not overly obnoxious which is good. It really fits the game. The controls were excellent. I had no bugs or glitches. Overall 4/5, 8/10
