I hope this is the best place to post this. Anyway, I came up with a fun little challenge from the original smw game on one of the ice levels.
The rules are to beat the level under the following rules.
1. You may run to gain some speed near the start
2. Once you jump over the spring board you can only press down and jump, nothing else.
3. try and beat the level.
Since I had R and L disabled I tricks to try and get the turtles to spawn sooner an order to be able to bounce off of them.
Also I haven't yet been able to beat the level under the current rules.
This could also be a gimmick that could be used in a hack where all of the buttons are disabled and you have to do a similar thing.
Let me know what you think.
You can watch me try here.
