It is not easy, in fact it may be one of the hardest games I have played in the jam so far....But it works and requires some skillful planning. Needless to say, I played and completed all the levels.
I think visually the game has this atari 2600 vibe that works well with the puzzley antics.
I think the puzzles themselves are challenging in a way that does not feel unfair. I really like the aim for the walls to mirror teleport, i thought that was very clever and unique.
Feedback:
1. I noticed a bug where sometimes the next tile is not the tile that gets played (that one hurt me in my soul one time)
2. A timer to warn you when the marbles will start rolling would be nice.
Overall, nicely done. I had fun.
