Ok firstly, I LOVE THE GAME MECHANICS. A Cube based world?? Brilliant. Those mechanics are some of my personal favorite. So kudos for originality and creativity. Then there's the core gameplay loop which is perfect for both the theme as well as for a hyper-casual game. Like I had so much fun playing the game. The animation for the rotation of the cube was also very well done. The music choice was amazing and I loved that each region had it's own sound - enhances the playing experience so much.
There is still some improvement that can be made though. For example, as much as I loved the sounds for each region, I felt like they were way too loud and became slightly annoying when combined with the actual music with the game. I did also find a small bug where on Level two I couldn't collect the berry - like the pie-chart above it wasn't filling - so please do look into that if you aren't aware. Although the game mechanics and the gameplay kept me wanting to play more, I do feel like there's still some 'satisfying' factor missing from it to keep the player's attention. It could be fixed maybe through some powerups or maybe character upgrades (like the character changes outfit depending on the region they're in or maybe after a certain number of levels).
I also had a few suggestions for the game, to maybe put some ideas in your head, if you guys decide that you want to keep working on the game. One would be that you could definitely make this a "multi-world" game. What I mean by that is you can have a specific numbers of level take place in one world and when the player completes those levels they move on to the next world (like the first world is Earth, then they're on Mars etc. The worlds can even be fantastical!).
Overall though, Love the game. Love the effort you guys put in it. Amazing Job!
