After every level, It’s Dangerous To Go Alone Take This Physics Breaker.
Since Physics Breaker was /way/ a better theme.
Original idea dump follows.
CAVE JIMMY 2: PHYSICS BREAKER
Platformer where it gives you a random physics breaker from a set, you have to use it to unlock more, various level sets etc. I do have working platformer physics left over from a past LD game.
Idea #1 –
Conwiz gives you a Conspiracy. You apply it judiciously to NPCs in dialog stuff to persuade them to give you money, etc.
Idea #2 –
YOU ARE ISLAND 2: TAKE THIS
It’s like You Are Island but slightly less crummy, involving real gameplay and not super tons of combos and goofy pixellation – a random bonus item at game start.
