Originally, this wasn't going to be a full game but I decided to release it anyway. The graphics aren't very good and the coding is a bit sloppy but it's still playable and I'll fix it if I make another version.
I know some people won't bother reading the instructions so here are the controls:
LEFT + RIGHT arrow keys - Movement
UP arrow key - Jump
SHIFT - Switch between your two playable characters
SPACEBAR - Rope up to your other character from a lower ledge
If anyone has any level/feature suggestions for the next version (if I make one), I'll be happy to include them if I can.
