==> Play now! (WebGL required) <==
I found this theme very challenging. All ideas were either way too narrow to be fun, or way too broad to be restricting at all. While I was trying to figure out what kind of game to make, I implemented the WebGL framework I needed in Dart, which involves quite a lot of heavy lifting, including having to write shaders. WebGL gives you almost nothing for free.
Once I had the framework up and running, I had no idea what game to make, so I temporarily ditched what I had to try out another idea. That idea sucked, so I went back to the original mess and slowly over the day turned it into a game about santa claus having to gather wood in order to be able to create all the toys he will soon distribute.
Tomorrow, I will tweak and try to balance the gameplay, add a titlescreen and a game over screen, and look into getting some sounds in there. For once, I’m not worried about running out of time.
