Love this! Great retro aesthetic like a true Game Boy game. My only critique is that some of the puzzles feel a little repetitive where the solution is simply to place your portal at the end gate, that one came up quite a few times. Boss fight was a little tricky too, I think the hitbox on the back side of the spikes is a tad unfair. But still really fun and had some genuine platforming elements which was nice to see! Great job
