played your alpha game there is a small glitch that lasts for like half a second, if you facing left or right and jump and while in air you keep pressed the opposite direction of character direction when landed the character will move forward 1 or 2 steps then stops and goes to the direction of arrows pressed it will be good if you could fix it , for near edge future game plays.
how to recreate:
jump
in air if character facing left press and keep right arrow down
in air if character facing right press and keep left arrow down
when character lands will move the direction its facing at landing 2 steps in front then stops and goes towards arrow key direction
also there is a slight problem with the game , when you try to jump under the bridge to next gap, it pushes u in front forcing you almost to fall in pit, its kinda annoying cause i want to explore
overall of game looks awesome, keep at it and will become some big thing
btw if will be a browser based game, you might want to lower ticks, the cpu utilization here is around 68 75% and i admit i don't have a to new computer, a i7 quad core 3.5 GHz only
