AlienRun Game

heres some tips
(1) at least have a dying animation before suddenly flashing the death screen.
(2) have some type of tutorial before the game starts. since it looks so similar to a mario clone i instantly went for jumping on the enemies and died.
(3) why 100 coins per coin? that's way too many, this is not a casino.
(4) PLEASE choose a better font for the levels.
(5) dont copy and paste the same graphic for the ground everywhere.
(6) WASD should work and using the up arrow should also make you jump. I may be sounding a bit picky, but most games let you use both WASD or arrow keys.
(7) some blocks are not placed correctly in the "grid".
(8) the moving platform is too quick and just the first level is too hard. Since you only get one life, this game is incredibly difficult for no reason.
(9) no menu

i have seen worse

Played your game. Decent start. If I may advise: On game over mention the Hotkey for restart. Also when a little animation for things appearing on the screen, like the bridge, would help maintain emersion.

cool

I hope you like it!
