Controls affect the learning curve.
This game is a platform. Smooth controls make or break them and in this case I was not too impressed. The dash was more problematic to use than to leave out due to the fact that initiating a dash means that you can't jump until the dash is complete. I understand that the reason for this is likely because of the dash's attack/invincibility aura not carrying into a jump, but it doesn't seem as though it would be that troubling for a game designer (or game-breaking from a difficulty standpoint) if the player were allowed to abort a dash attack by jumping at any time while they are on the ground. Smoothly carrying the momentum of a ground dash into a jump has been present in gaming for over 15 years so to leave that out I take as more of a design flaw than anything else. Nevermind that because the dashes are activated by double-tapping the movement key, which as another reviewer said can lead to you dashing while simply trying to move at all. Obviously some people can get past this but that doesn't mean that a dash button (or a key remap, although such a function seems to be anathema to indie games as a whole rather than an isolated case like this so I don't dock you for not having it) wouldn't have been helpful.
I do like the graphics and the sound, but the platforming leaves something to be desired for me.
