Hi, this is the best time game I think for mobile. I have a few things in my mind that would be great to add/change in the game:
1. Level editor, make your own levels and play the ones from others
2. Change the dual, such that the fake ball doesn’t activate the falling down tiles. This will result in some fun gameplay
3. A ball speed change, when the greatest part of a song in RS is on, you can speed the level a tiny bit up and when that part is over, you can slow it down a bit. So instead of the big speedchanges for a small time, make it that it speeds it up a tiny bit/slows down to fit in with the music
4. Make a second dual, where both balls will follow the same path instead of a mirror path. You have a row with: empty tile, ball 1, empty tile, ball 2, empty tile.
5. Change the design of the current dual portal. It is really big and it blocks your vision. Maybe change it as the way you see the checkpoint, but with a different color and icon.
6. Add some events with small rewards in levels like ‘the winter’ event
7. Give the first levels in rolling sky crowns and maybe less gems, just like the level forest.
8. Continue updates forever, it is definitely a awesome game and I can’t wait to see what will happen in the future. Keep up the good work!
