Its a funny arcarde.
I would let the player store one or two power ups and use them when he wants
Glad you enjoyed! Yes, having manual control over powerups was something i considered, but never got around to implementing
maybe you can add slots if all have a power up when pick a new one, triger one at random and fill the gap with the new power up, or you can trigger one pressing the slot
That could be an idea - theres a lot of different ways I could implement them!
