The game has nice, simple pixel graphics and a streamlined feeling. The puzzles are nicely done!
One thing I would give as feedback is that it is difficult to know what is on the other sides of the die. It was also not clear what to do in level 5. I thought I had to match the die with the numbers on the blue dice so I spent a lot of time trying to figure out what to do with that. But apparently you can just go through the left.
All around great game! Would be nice if you gave mine a shot too, it has a similar idea!
