This did not grip me all that well. Changing your size is a neat idea, but I unfortunately see no reason to ever change my size until I've collected every cube assigned to my size. Everywhere there is a big cube, there's a small cube, too. It seems more optimal to me to just be big to go pick up all the big cubes before shrinking down and doing the same walk all round the map to pick up the next set of cubes and so on and so forth since I'm at least doing something rather than waiting for the cooldown to be over so I can pick up one cube that I'm already next to before doing the same process at the next set of cubes. A way I think this could be remedied is by having clusters of cubes of one size permeating an area that would incentivize the player to switch sizes since there would be some good value to justify taking the cooldown. Taking the cool down to pick up one cube isn't too appealing, but if 1 cube became 5, now we're getting somewhere. The area is also... Massive. Like, really open with not a lot going on to keep me interested, unfortunately. I also can't seem to go below a certain Y level without dying no matter my size? There's some low bits of the map I can't access at all because I seem to just die and I can't figure out why. All and all, I think there's an interesting idea here, but it just leaves me wanting something more as I walk slowly across the map towards my next cube in the distance. Anyways, I hope I haven't come across too harsh here with my thoughts. Good work on releasing a game, especially since it's a 3D one. From my own experience, those tend to be a bit harder in getting them to function and play well with itself, so you have my respect there.
