Nice game.
1, The character moves too fast.
2, The wall jump is clunky.
3, If you get the wall jump. You can switch the blue rooms and cause the beginning room to appear, then you can wall jump out from the hole you fell from and go out of bounds.
Besides these. I think this game can be expanded Into a full metroidvania some day.
Also, I would be very happy if you would play my game.
