Fun game. Has simple tile-based puzzle mechanics yet fits well with the theme. The level designs are quite smart, and I faced some interesting challenges trying to figure out the paths.
1 concern is, I struggled to understand how to join the cubes. After the 2nd tutorial, it was still slightly confusing that the joining of cubes need to be directional (like you have to go right/up to increase the cube size), but got the hang of it.
