It took me a little while, but I came up with a game idea for “Everything on one screen” AND “Snowman” 😉  You play as a Snow woman that has to collect stolen presents to save the Holidays! Each level will be contained to a single screen, similar to Pacman, Towerfall, ect. The levels will also be populated by random hazards and enemies.  At the moment I don’t plan on adding any kind of player attack.  Instead, the game will be all about avoidance and speed.  So far I’ve got the player movement working, presents, and the door to go to the next level.  After I get some sleep I will start working on enemies and traps.  I’ll probably get a few more levels prototyped out after that before I start working on the actual artwork.  Here’s the progress so far:  http://s24.postimg.org/l8bhrk5r9/prototype.png
