Gearful

Hey, fun game, I definitely liked the progression of difficulty throughout the levels as well as being able to rotate my gear on any surface. 👍
I didn't actually get how the bubbles worked until the third level, and just figured out I can hold space and up to jump a bit higher after a while.
I'd say keep the hold longer jump thing if it had it's own level explaining it, as it could be a good mechanic, as shown in stuff like Super Meat Boy, which this reminds me of.
It would be a major plus if the bubbles respawned after something like 3 seconds, so you don't get trapped in the second room, or maybe have one type that respawns and one that doesn't, and then just show you can press something like R to restart the level for the ones that don't respawn.
In the last level being on the moving gears made it to where it was hard to just press jump, I thought maybe they were there so you could get some momentum before going on the bubble but, it seems like you just cant jump if your moving on one of them which was strange, maybe make a level where it explains where you have to stop to move on them? Also the jump from the bubble to the wall was a bit too far I think :P
I look forwards to seeing more in the future, I could see you being a master at level design if you stick with it!

Nice game, I really enjoyed "gears" and "bubbles" mechanics But music has stopped and spikes sound is quite annoying
Btw, this is a good game
