Thanks for the positive feedback!
I'm glad you liked the simple graphics as well as the concept of my game!
I understand the lack of mid-air movement control. It's something that I definitely have to look at a little more carefully next time. I tried to design the map in a way that even if the player falls, he would still be able to find his way to go up again. I've also included some guidance arrows, but I guess it didn't work out as well as I planned!
EDIT: I played and reviewed your wonderful game! :)
