Thank you so much for playing my game and for all of the feedback! I agree that the movement speed was kind of slow and is something I will fix if I continue to work on the game. When I first started working on the game the plan was to have a larger separate area for each gem and allow the player to pick a weapon/boost they preferred to play through each area. When I started running low on time and downsized the game I didn't go back and change the mechanic to stacking the boosts which would have probably made more sense for the size of the game.
Anyway, Thank you again for playing my game and leaving the feedback!
