i absolutely loved the speed & how beautiful the game looks, the srb2 inspiration is coming through very clearly because it feels just as smooth. only thing i would say is maybe make the enemy pickups pop out just as soon as theyre killed though, or even automatically give the reward to the player - waiting around can kill a bit of that speed in the otherwise satisfyingly quick combat
We've been considering changing it back to automatic rewards, we are also playing around with the idea of juggling enemies for extra reward.
