So honestly I don't have any concrete plan on the structure of this hack yet. I'm just gonna design whatever kind of levels I feel like and go from there.
Here are some screenshots:
That Kaizo Feel
This is gonna be the first level. No custom stuff besides the music (and a gradient when I decide to add it).
A castle level based entirely around the Punchy Boxing Glove gimmick. I've been meaning to do this for awhile.
So yeah I'll just post updates as they come.
