Cool game, I like the music and the simplicity in both game design and arts.
It is still fun to play, though.
In Viewnemy you are in a completely dark tower full of enemies and traps.
The funny thing is that those enemies will help you to climb the tower using their faint light.
You need to clear (turning off all enemies) the whole floor in order to pass to the next level.
EDIT: I uploaded a new version in HTML5, adding "B" as another button to jump because lots of you didn't like the "X" jump position.
You can still play the original flash version down below.
Unfortunately I ran out of time so I made only a few levels, but I hope you enjoy it anyway. :)
