I recorded some gameplay:

no commentary, link expires in 3 days.

I needed to edit the video, because I was recording in full screen, and whenever I needed to restart, the esc first gets you out of fullscreen.

There are many ways to soft lock yourself, or get stuck. You can see that in my video.

The levels are too open for a game where you need to get bolt in correct order.

I wish there was a dedicated key for quick restart.

Couldn't get past the Lighting door in level 1. The first Lighting key seems impossible to pick up. You can also easily softlock yourself a lot of the TImes. And I don't really see any nonlinearity. You could go pick the left key up first, but then you'd have to just completely backtrack to get the right key, and then backtrack again into the left. Theres no looping around or anything. Theres an Area with a few Stars in it behind a wooden Plank, but thats only openable from one side as I see it, so I couldn't get there. Music gets annoying after a while, maybe it changes on different Levels, but as I said, I was stuck right in level 1. 

From what I've seen scanning through the Comments and watching that YT Video, its me being retarded, not the first level being impossible. Should've probably jumped on the Barrel(?) But immediately got it stuck under the ramp on the left and couldn't get it back out. I lost interest after that. Its just not my kind of Game. Sorry.

Audio slider please. Sound effects sound a bit harsh, I'm not an audio guy so I don't really know how to describe it. A lot of softlocks but its not the worst.

This game has infinite number of ways to get yourself stuck, but it's not a big deal with a reset button. It controls well for a ball, but not quite enough for any precise platforming attempts. That one secret was nice.

It's very easy to get stuck. Momentum is weird where you can't jump when going fast or getting hit by spikes means being stuck with them since there is no frames to allow the player to escape.
