Cool idea of the gameboy, doesn't really fit in with the theme but great job making an awesome game nonetheless!

i loved the music but how is this mutation exactly?

cool that its a game for a gameboy but im not sure how its uses the mutation theme? its also really hard to control a game boy with a mouse lol. nice game tho

I like the idea of the gameboy

Not quite managing to get a exact grip on how this is connected with momentum specifically, besides being able to move and jump (jumping actually quite nicely implemented, with the use of a "boosted" jump, following consecutive jumps, short after each other). 
Interesting idea of enclosing the game into an old fashion Gameboy of some sort, makes the control a bit fiddley though.

I'm not too sure how the theme is interpreted here, but the concept of playing in a virtual console with handheld controls is pretty neat! Had a bit of fun playing around with it!
