proper falcon
Concentration: lore accurate gamemodes. The wave would be curved like an actual wave, the spider would climb up things instead of teleporting,, and the ball wouldnt be able to change gravity, but instead bounce off of things. Each gamemode would be modified in some way.
Brainstorm: Pluto travel - You start at mercury and get to pluto (Idea is from megahack lounge)
Scamper: Deadlocked, but you play as the monsters/moving objects in the level. In the ufo bossfight, you could use a ship to control the height of a laser. In the first ball part, you must tap only when the player is on a red platform. During the 80% memory part, you move blocks to kill any players passing through. This would be best as a minigame level made in platformer mode.
Ramsey: A level where you are a shooting star and you must avoid collisions with other space objects as you get to earth. You start in the asteroid belt and as you make your way closer to earth, the satellites begin to notice you, and you must avoid lasers from them. You win by reaching the ocean of Earth. The endscreen would be a view from the land of the sunset, but the meteor would light up the sky as it crashes down. (https://en.wikipedia.org/wiki/Meteor [redirected from shooting star])
