So, just going to put the list down as it comes to me or as things are suggested... -Magnetic Blocks - Could be used to fight/cancel gravity by attracting or repelling things or the character if you're wearing the right kind of metal? -Antigravity Blocks - Simpy blocks that try to float up -Bouncy Blocks - Because trampolines are fun! -Acceleration Blocks - Simply make you move faster whenever you're touching them. (Thank you Portal) Hopefully I can update this with my and other's ideas.
