Fun experience, the level/puzzle design is top tier, the "enemies" get reused trhough the game but they are always used in a new way making the game very interesting. Liked the first upgrade mechanic and also the way you join it with the second and later with the third, making so you need to use all of them. My favorite part is how theres no loose state, making it almost like a foddian games at times. I do got lost after collecting the last upgrade and returning to the initial area as exploring around I didnt find any places that where blocked by the red laser, besides the one you just arrive from.
