Thanks for trying out the demo! We'll try experimenting with tighter input delays, see if that solves the snappier issue. Why do you think the dash should be longer?
It's more of a feeling that the dash should be longer. Playing games like Nier: Automata have spoiled me as a player into feeling that longer dashes aren't a burden on gameplay, but only enhance the experience by allowing a better dodge mechanic and easier time travelling longer distances. Liken it to games that allow players to dash; which game feels better: The game that has a short stamina bar, or the game that has either a longer stamina bar or does away with it altogether? In the end, that question will be different for each game, but I feel that at least for this game a longer dash (at least by double) would feel better
