Not bad at all! It does feel satisfying to get all three cubes into the goal, the levels look quite cool like I was being used in some sort of futuristic lab's test area and the particle effects that would shoot out whenever a cube bounced were nice to look at, I like how each cube has a roman numeral on the top side you didn't even need to do that but you did and it's a nice touch. The controls are a bit weird to get used to as trying control 2 or 3 cubes was hard to do with accuracy or precision, jumping doesn't feel responsive even if I hold it down as long as I can, using the yellow launch pad would leave on of the cubes stuck down there 9 times out of 10, trying to gain speed is pretty hard if you aren't holding a direction down when being dropped into the level, lack of music is another complaint I have. It's not bad and has polish just needs more refinement in the controls and a few mechanics is all
