I started on an in-game level editor/sandbox thing, and it will be the very last level in the game.
Platforms that fall down when you step on them. They can actually go in any direction, not just down.
I made a few levels for world 5, which takes on an art style similar to Double Action Blaster Guys. I made a video
showing gameplay, and also showing one of the world 4 bosses.
You can fight Forehead Block Guy! He's the new World 2 boss. He walks at you while continuing to throw blocks.
The first world 4 boss is my old Fighter Maker 2 character, and he has three attack phases, where he first attempts to kick you, and then attempts to bodyslam you, and then does this trickier attack where he flies into the sky and stomps. You hurt him a few times to get him to move onto the next phase.
The second World 4 boss is on the background layer, so I think the boss fight will end up involving platforms made of sprites. Not sure past that.
I think I'm actually on track to finish this game this year, probably in June. I only have a few more levels and bosses to make, and I've gotta apply the rest of the polish I wanted to have as well as put the soundtrack in.
