Jumping doesn't seem to work. I tried it with 'W' and the up-arrow, but the slime just won't jump.

It's logical game... you need to evolve to jump :)

If I died I needed to restart as the jump evolver thingy didn't detect me. Kept getting stuck in walls when I rejoined. Real shame because I can see lots of people getting annoyed and quitting what is a very nicely designed level.

Would love to play it without the bugs and liked the resolution choice.

Very challenging, I liked the puzzles. Took me a while to discover how to jump :P

Good job!

I like how you did the theme in this. The jump seems to lag at times leading to some annoying deaths.

Oh! I forgot to disable default GM key so...
F4 = Fullscreen
F5 = Save
F6 = Load

And i'll try to fix as much bugs as i can.

Great take on the theme. The music is the most annoying thing to me in this game. But plays nice being muted too. Love the look of your game and it was a lot of fun playing.

I just can't get how to jump or how to reach this strange thing in the beginning :(

It seems that many people need little hint. :)
That smashing trap door don't kill you! ;)

I liked the initial puzzle really, really much! Brilliant! :D But the buggy platforming made me sad :(

great and awesome introduction, i didn´t think hard, I just try more than 4 times, maybe if you change the color or accentuate the key thing, could be better to understand... Congrats for this entry...

oooh! now I get it :) Very interesting idea! But looks like something wrong with collision detection.. i can't take this jumping thing on the second or third try..

By the way: I really liked this music :)

Won't work under wine. But it looks great (like professional game).

I just fixed bugs with merging and wall jump! Am so happy!
I started uploading update but it will take a while. 4 kB/sec!!!

Nice little game :) Maybe I'm doing it wrong but I can't seem to wall jump. Is wall jump a powerup that you have to collect?

Found this really hard! If someone can tell me what to do when I get to the bit with what looks like a door and some red blobs on the ground, I might play some more :) One thing I would fix is the jumping mechanic. It's counter intuitive that you have to press up first, then left/right - I kept trying and failing to do running jumps before I realized this.

Good challenge and little game :) I love music :p

Fantastically done; your ideas were brilliantly creative. The raphics all worked well together, with exception of that one boulder sprite. The puzzles were great. Engine was mostly solid; a couple collision bugs made apparent in the portal reference. Remember to limit your vertical speed. Overall, very well done.

So there's another tip: buttons pop up when you pressed wrong button.

(wall) jumping doesn't seem to work for me.

Needs instructions. I don't like games where I can get stuck less than 2 seconds into the game. The first puzzle should have been more straight forward. I would not have figured out how to jump if I hadn't of read the comments.

Got the jumping, but then I'm stuck. I had fun!

level design needs a bit more thought, the potential dead ends right at the start are kind of a bummer. some nice ideas though.

liked the music, but after the first puzzle i just kept seeing myself jumping into lava :?

I Couldn't get it to wall jump, I look at the readme and stuff but I couldn't get it to work, otherwise looks like a cool game, great music

This game is very good! It has a lot of features implemented and I love the music. Gfx also, the boulder is a little off though. Just to be picky on something... :)

I have not played your game because I have a mac and a windows laptop that probably won't work. It looks cool though. This my first LD also but i programmed in visual basic. :) My game is probably worse than yours but check it out if u want.

Very nice and challenging puzzler, the halving mechanic is really great.
Platforming could be a lot more fluent and precise, though.
