The bosses are interesting, although the second one feels a bit impossible. I think there should be moments where it lets you catch your breath a little—I’m not saying it should stop attacking, but maybe have some less intense attacks at times. This, combined with the super long cooldown for dashing, makes it quite a tough challenge. I think there should be a cooldown indicator; you end up spamming Shift until it works.
Despite all this, I find it a fun game, and if you update it, I’d gladly play it again.
One more thing—what’s the ability you use with “E”? So far, all I know is that it takes away half my health.
And finally, wheres the control list? At least on the game’s page. I don't know if I used all the keys.
