This game makes me go YES! 

Rather confusing and the controls were a bit finicky. But you have a good idea here

Once I understood how it worked, the experience was really fun.

But it was very confusing at first.

Also the lighting makes it hard to see what is happening sometimes.

There's good potential here.

What a great idea and the mechanic was unique! Yes  the visuals aren't the best but for a solo project aceptable.  Well done!

Neat idea and concept, although I found it a little dis-orientating. May be changing the perspective or giving visual feedback to the player for the transitions will help. A good job puling this together regardless!

I really like the mechanic and I think it can make an interesting game. I do have some issues however with the feedback the player is receiving and think this concept might work better as a third person game. Reasons for this is, activating the main mechanic takes away vision away from the player, the player has no idea where they are exactly or where to go, this makes it frustrating to go through the level. If it were a third person game, you could see where you enter the ground and how far the next platform is, this already gives plenty of more feedback than first person.

Interesting concept, but I feel that it's a bit too easy to fall through the object you're sinking into so you know if you're going to fall to the bottom of the map, or be able to let go of space and shoot back up into the air.

Great!, I liked the mechanic, specially keeping the momentum on landing while pressing space to jump even higher when returning to the surface, and once I got the hang of it, I felt like a pro jumping between platforms! One thing though, it was kinda hard to understand what was going on when on a tall platform, and hard to guess when I was about to reach the bottom of the platform and fall to my end. But overall, nice work!

It's fun! I liked getting into a flow of sinking and jumping. Nice mechanic. Most of the time I  got lost while sinking into the shapes.
