Interesting submission, I really liked to play a Game Boy styled metroidvania. I loved the "overworld" mario-like aswell, pretty nicely done. It's a little buggy tho, my HP got stuck at 19 and I was pretty much invincible and the game is a little too slow paced for the size of the map and for how many paths you can take, making tedious to go all the way back when needed.
But I enjoyed it quite a lot!
