The game is really nice but I found some problems:first,I cant jump over that pink box to reach the other part of the area(I pushed it to its place but i still couldnt).Second,when you change screens It might happen that you cant move anymore.Third,the jump height is like you would be hit by an invisible wall,I just literally pushes you onto the ground as soon as you jump.The last problem is that its that the game Is laggy(but maybe just cuz my laptop is bad).But since its a demo i wont say it is bad,I see a lot of potential in it,but it really has some problems to deal with.Good luck.
