On one hand, apart from the lack of sound effects, I thought this was a pretty neat precision platformer with solid presentation and a decent set of mechanics and obstacles to go through, and I always like a challenge.
But on the other hand, I had a really frustrating time with this game in contending with the controls: for some reason I just couldn't get the bounce to work consistently, particularly when trying to go for height, as it just felt random on whether it would get height or not. I tried all sorts of different methods to get it to work but it felt like I had to fight the game every inch of the way just to have it work with me.
Even taking my issues with the bounce away, the game just felt overly slippy/bouncy and too fast all-around, as well as way too short with the levels getting way too hard too fast to make up for that shortness. A good attempt, but precision platformers like this need to be extra solid with their controls to make everything feel fair, and this felt very confusing in that regard.
