I just tested, I really love the game! Very nice idea, love the gb vibe, and quite easy to understand what needs to be done.
On mobile I had some display issue, even in full screen I couldn't see the settings button completely. And when I arrived to the hyperspeed level or something, I got completely stuck.
I tried on laptop and it was much more enjoyable, though in that hyperspeed level, the camera doesn't seem to turn for some reason, I'm always facing the same direction, but maybe it's intended. Using the map helped finish the level.
One thing I found a bit weird is that it seems a bit unbalanced with enemies. Sometimes I get a few levels without any, sometimes I get 3 on the first level. One time I got touched before I could even ping.
But overall very cool game, would love to see where it goes, very well done !
