I like that blorb lives in a big blorb house, it should have some blorb little windows too.
BGM music on dialog box scenes should be looping, it stops after 1 play through
The camera shift when you change direction, to keep blorbino roughly 40% to the back side, it is quite swift, at first it felt like a glitch but then on playing with it and you see how it worked it not too bad but if it can be refined somehow that would be better, maybe when moving in a direction and his screen position is in front of where it "should" be then move the camera 1.5 or 2px for every 1px blorb moves until caught up or something idk, there is probably a way to make it feel less abrupt, as it is now it is too noticeable and draws attention to the camera rather than the game through the camera
Nice Music/SFX
It would be nice to split the background MSPaint art into two layers, front one colour keyed or png transparent, and at a different scroll rate for parallax effect between light green hill and dark green mountain
It sometimes looked like he should have landed but I think maybe his red shoes misses, sometimes there is trouble rejumping on a 1block platform getting ignored I think it might be browser input lag or something, maybe when let go and repress space while game thinks it is still jumping, flag that and queue and immediate rejump on land?
The overworld needs arrow keys but was playing with AD so it looked like couldnt choose anything and only the first level was available so played the first level again then realized it is arrow keys only on overworld
cool that he flies down from the sky to enter the level
the flying red potatoes were too OP for me
