awesome game, the dopamine you get from going really fast and being above the platforms is unbeatable. here are some things i have to say
• a shield powerup would be cool. it sounds generic but i have an idea to make it not as generic. when you fall in the void with a shield, you lose it and you get a boost upward and forward.
• make every item have a specific beam color. its hard to identify which item is which when you are like a million feet in the air, so this would make it easier to tell.
