platinum style character action game where the player character gets around on, and attacks with, super sharp weaponised iceskates. it could have really cool parkour movement and fun combat
a cycling game where you control the balance of the bike by pressing the left and right arrow keys in time with a slider that bounces left and right. the slower the bike the faster you need to press the keys to keep balances, speeding up makes it easier just like how a real bike works with gyroscopic forces. if its too easy maybe make it also go down hill and be mountain biking lol
