There a couple of interesting puzzle mechanics I hadn't seen before (like the arrow). However, the visual effect is quite nauseating. You also re-use large parts of levels, in levels that are right after eachother (kinda defeats the purpose of a puzzle game). Your screenshots show that the game can be controlled with wasd, but only the arrow keys are supported.
I've also noticed that I often get reset to the beginning of the stage when I fail a level, but sometimes I can just redo the level. It is pretty annoying to be reset to the start of a stage and having to redo a bunch of level; so I don't understand why it is implemented in this way. I made it to stage 3, to the level with a truck load of portals and the end goal in the bottom right. Since I kept getting reset to the start of the stage, I stopped playing.
