Eli and I have been working on a game using Game Maker (download here) called Mario Bros. Basic. The objective of the game is to make up as many silly and tedious levels as possible. Here are some screenshots.
This is the first level.
Here is the "wet basement" level. You can see by the fireballs that we still have a few bugs.
Here is a level demonstrating the use of "fire blocks"
When we "finish" we will post it on yoyo games and I will write a notification.
