So a few things...(since post-jam release is planned).

One is that I did not quite understand how to progress (or what is progress). Two is that the control is a bit surprising as when I see a player I just assume WASD is moving and jumping. This is a relatively minor point tho, because I got familiar with this fairly fast. The third point is a bug I think, after I merged three blobs together and unplugged (not sure what this means), I got a sort of big gray area with no character nor any enemies so I was stuck.

Liked the sprite artwork in both modes, I think it has great potential.

In conclusion, I think a bit more refinement including tutorial and mechanics explanation and some debugging is required.

I'm a big fan of the sprite work and style going on. It feels very professional and modern.

I like moving the big blobs. It was fun.

Awesome idea and slick transition between modes. This looks like it has great potential!

I know you mentioned that this game was incomplete, but honestly there's a great foundation here. I was having a ton of fun seeing how much speed I could build up skating around the edges of the pools, and I thought the feel of launching the pools at each other and re-arranging the map was perfect. Can't wait to see how this progresses, nice job!
