Nice, cute looking game. :)
The "ladders" are a bit weird though. As you can get hit by spikes while climbing up. And you can't really adjust the exact spot you are climbing easily.

I love the player sprite. But the difficulty was really high for me and I wasn't able to finish the game. Bumping into the platforms above me and all of the leaps of faith were too much for me. 

The atonal, chaotic music is very apocalyptic - which was fun at first, but then it got very hard on the ears. 

I was playing on GBC and the shades of green that are used are very dark - it's actually not a very high contrast with the black background. You may want to tweak your color palettes for ease of visibility.

I like it. Good sprite. Gravity of gbstudio platformer is a little too hard for me.

A little tough at times with the close spikes and leaps of faith, but I often enjoy platformers on the more challenging side and the instant respawn instead of lives made this very enjoyable!

I got to the boss but was unsure what I was supposed to do? The best I could figure out was just to survive and dodge the falling rocks, but I would always die eventually before anything happened :P

Also, I thought that the main character's sprite was very cute!

Nice looking game! I love the character and background graphics - very beautiful. And there's a cool story. The controls are a bit wonky (slow but high jump, slippery), and the margins of error are narrow, which makes the game very hard unfortunately. It may be just me, but I can't even get past level 2, sorry to say.

Super fun, love the art style :)

I really like the tile sets and character! I’m not much of a speed runner but I tried my best! Thanks for sharing your game I had fun playing it!

A little unforgiving but fun! I like the story that you framed for it

I liked the game a lot, I think you didn't have time to implement collision sounds with the enemies, and for me it lacks a timer, or indications to see where we are during the boss (which by the way is excellent! It took me 5/6 times to beat him, with a good level of stress : D ).
