This is hella fun, but the Sword+Dash interaction needs to be nerfed; as-is, it trivializes the entire game. (Dash makes you invulnerable for a set length of time, rather than just while you're moving. Sword stops your motion. So if you just keep spamming Dash and Sword you're permanently invulnerable while also having control over your movement. This is possible as soon as Sword's cooldown hits level 2.)
