The Potato Man Adventures

it is nice to see another beginner game developer like myself. i guess this is one of the first games you are making. at least that is what it looks like to me.
the only real bug i encountered was that sometimes an enemy clips through the wall.
A bit of sound will improve the game drasticly. google bfxr. the first link. that is a simple sound generator free to use for any purpose.

just keep developing your game and you'll be better in no time.
i always quit my little projects loong before they finish and i regret that. please don't do the same. make and finish small games and you'll become great at developing games.
