really punishing platformer. i enjoyed it but didn't get very far haha

Had a bit of trouble reading the spikes at first. Sound and music are really nice, felt very gameboy to me. I really enjoyed looking down. I thought that was a super useful mechanic and well executed. 

i like the gameplay the art too .

it just a bit hard to see the spikes 

Its a good game with nice sound and music. I'm never a fan of up for jump but I understand why you did it. I agree that with others that the spikes are hard to see, I had the same problems with the 4 colours with my game. Checkpoint at each level would have been nice aswell so we could finish your game

First of all, good job guys and girl!

I enjoyed the pixels, the mastering of sound "blips" and at the end ....the game! It's a true game! But please, make the  danger predictible...deadly spikes are too much invisible and deadly;)

Not my cup of tea but great job :) 
Think I reached level 3  as my best and I tried a lot of times ^^"
One big issue was the spikes that was the same color as the background, kept jumping on them by mistake as they blend out so easily. I also had trouble to figure out how high of a fall you could survive, it seemed to be longer sometimes when I fell by accident and survived but I guessed that if you do a small jump the threshold still becomes to large and you take damage.  
I would probably have played a bit more if it was easier.

Nice concept! I like the idea of a punitive platformer on Game Boy. Would love to play it as a kid.

Sadly I stopped at level 3, putting the jump input to the Up-button instead of A or B makes the game really hard for no reason. I think the game would've worked better if we remove either sprint/attack button in order to jump with more precision. 

I left a comment on the game page, but I think the game may be a little too hard! the spikes are hard to see and their hitboxes are bigg. But the game artstyle and sound is nice!

Stellar sound and artwork. really captures the gameboy soul. the hitboxes of the spikes are unforgiving. I could not get past the drop in level 2 - whats the secret here?

furthermore - are you sure the keybinding for sprint is "X"?
