I was very impressed with the core mechanic, the reflecting beam of light was a lot of fun to control in the levels. The audio also adds a nice calm touch to the gameplay. The level design was quite exciting to traverse, I was thoroughly surprised at the last level and honestly found myself wanting to keep playing, the potential levels that could be created seems like it could be amazing.
I did find myself clipping through some walls, especially the level end gate at times, I also hoped for a sensitivity slider, just to turn down how fast I seemed to be moving.
But other than that the game is well executed, and has such an enjoyable and expandable core mechanic.
