Climb the Tower
A downloadable game for Windows
A rather difficult and very short platformer with a hand-drawn art style, a dynamic soundtrack by the infallible David Firth, and an ending with too many emotions to count, brought to you by the geniuses behind 'Mediocre' and 'Run Away from the Nuclear Explosion'.
You're timed, so you could play over and over again to try and beat your best time if you're into that sort of thing.
Unzip it and run the executable you dingus.
