Accelerating wile moving is fun the arstyle is choesive and the movement feels smoth and the partical effects are great , i think it would have been a little better if the players initial speed was a but higher, also i think beeing able to use a lot of your carge for a shield/life up would have made the charge mechanic more impactfull and reduce the number of times sections have to be repeteat, also jumping would have been a lot better if jump height was linked to how long you press the imput key , also geting your charge repleneshed when dying, also the spike colision should be a bit bigger i landed between two. Overall the game works well and never crashed, i ran out of time in the 4th level.
