This project is the result of combining Bonkers Sewer Adventure and Banana Nababa 2.
Here is a few vids to showcase what it's like:
Controls are Z X C + space + arrows
You can press B to go directly to the boss in each stage. To get back to the stage selection, simply commit suicide and choose Exit.
Theres 3 stages, none of them are quite complete and have a few dummy rooms each but Toy Factory is the closest to being done, Greenhouse is second and Sewers is last.
The plan is to only have 4 levels from which these 3 must be completed to advance.
