Interesting game mechanic. I enjoyed the novelty of it, the art is nice and simple to get the point across and of course there is some juicy sound effects for that dopamine.
However there is clunk in the controls and overall gameplay feel was not there. For example, the bounce strength from the ball being high, the slow heavy movement with short jump of the player, the lack of fine control over your character to position yourself correctly, all introduced a lot of friction to me as a player.
Also, the levels are simple enough to complete with just the ball and triangles alone, I don't really see the point in being able to combine any of these.
Also there's a bug where if you touch the wall you get stuck :(
