Here's what you can expect to come next demo:

1. Insane World (World 4), consisting of two of the weirder levels in the game; the hippie themed Forever Flowery Fields, and Lightning Rod Lake, which is similar to DKC3's Lightning Look-Out. I'm attempting to balance them so they're around the same difficulty as Ludicrous World, so expect them to be difficult but fair.
2. Unlockable characters! The Anti Freaks and X-Freaks aren't just there for show. By collecting trophies, you can unlock all of them, as well as a few other characters I have planned. They're all basically just skins.
3. This one is more a maybe, but I'd like to strip out my custom controls and swap over to using the excellent Input library by Juju Adams and Alynne Keith: Input by Juju (itch.io). The catalyst for this was trying and failing to add button icons for single Joy-Cons, and even doing the Switch Pro Controller was kind of weird. No need to code something myself if something better and way more comprehensive than I ever could do exists! I'm just hoping it won't be too difficult to pull off this overhaul. If not, there's always next game.
