Many years ago I created this ugly picture of a snowman in MS Paint. Every New Year I would change the last digit(s) of the year and send it to my friends, wishing them happy holidays.
This year I decided to make it into a game.
I present to you something you've probably never seen before - a mix of Super Mario Bros and Doom! (and some other stuff)
There is only one level, but it's full of secrets, cheats and Christmas eggs!
--->>> LINK TO THE GAME <<<---
The game will open in your browser. You can play on mobile using touch-screen controls, or on PC with keyboard (recommended).
Turn up the volume on your speakers and enjoy!
:)
Big thanks to
