Hey! Interesting idea :)
Visual
Visually, it's really simple, but it doesn't feel weird so it's okay
Audio
The BGM is nice, but it misses SFX, when you finish a level, when you create a cube, etc.
Tutorial
Nice little text tutorial, but maybe a bit too long to explain everything.
Gameplay
- The movements feel too slow, and sometimes I feel like I move more in one direction than another. Pretty disturbing that it keeps moving when you release everything.
- The last level feels a bit brainless, I just popped 2-3 cubes and waited for the item to teleport in one of them while mindlessly roaming.
- The camera is weird, I often don't have the item in sight because I'm too low, or too high, ...
Fun
I played the game until the end, but it rapidly felt repetitive.
Bugs
I once encountered a bug where the right movement was still going when I released my right key, but I haven't reproduced it yet. I had to quickly press the D button to stop moving.
If you spam the "spawn cube" button before pressing "E" to start the game, you automatically win
Theme
I guess it's in the theme!
