The intro is fantastic and the art and music are great! I liked the controls and the way the new objects and difficulty was handled. I didn't get to finish the game though as I had issues with collision and sprites deciding to live in the walls! I guess he didn't mind it down there after all... 
Great potential! Good job! :-) 

Although the controls are in need of polish there is definitely a potential gem here.

One thing I like is that you get to figure our the quirks of the different characters on your own, rather than having an info box tell you.

Clicking the blobs while they're air born seems to require  a bit more eye coordination  than I can muster, so I did not manage to get very far. Perhaps there could be a slow-motion option?

I tried this game multiple times now. The idea of the game is nice, the levels too. But as the others point out, the way you choosed selecting characters it's not good. Selecting the characters with the mouse make it easy to block the player from finishing the level. You may think changing it with a key.

Overall the game is enjoyable.

Hey,

nice little game you made, really like it. played and rated.

Please feel free to play and rate my game:

Nice game, well done! I like the intro story / cut scene -- must have been a bit of work.

The puzzles are nice, but I was actually having more trouble just controlling the characters so I didn't really get to engage fully with the puzzles. I'm not sure if this was intentional and you were going for more of a tricky platformer style.

Overall very impressive for your 3rd game ever. Keep up the good work. :)

Oh, so you like slimes too? haha :)

Really interesting gameplay idea. Also I liked that you put some effort on creating a story.

The art is nice and cute, and the controls of the slimes are enjoyable. I liked jumping and moving around with them!

Cute and polished game.

That's a great job!

I like the little cutscene at the beginning to introduce the story!

The slimes feel a bit slippery but I'm guessing that's intentional! I didn't realise at first it was just arrow keys, maybe enable wasd as well as a lot of people are used to that? I think maybe also have some hints to say what the controls are, and how you can e.g. select multiple slimes.

I like the puzzle design, and sound effects. Well done :)

Nice idea. The graphics are cool But the controls are a bit odd. Maybe there is a point to it but I felt confused by the fact you can select and move multiple slimes at once. And also the camera recenters automatically on your selected slimes, so you have to deselect a slime to select another :)

Other than than, it's pretty cool !

Nice, I like the art and the music / sfx fits it well. The controls were a little confusing at first, but I eventually figured it out (also please support WASD because my keyboard is small and uses a Fn key for arrows :/ ). The characters were pretty easy to move and I like how you taught the player different things as you go.

Still in development. Also note this is the third game i've ever made, so it'll be a little buggy!
