Lich, Please!

Isometric 2D game, shift to dash, left-click to place barrier which will disappear after 30 seconds, space bar to activate melee weapon,  which upgrades 3 tiers upon reaching specific kill milestones, at similar milestones, 1 of the 3 bosses will spawn, both of which must be defeated to win, and TAB to arm the ranged attack once unlocked.  There's a low chance of finding a Sanctuary, which protects you and insta-kill all normal mobs, which will still chase you will you're in it, but it'll disappear 4 seconds after entering it.  Can pick from 1 of 3 perks on every level up!  Arrow Keys &/or WASD to move, of course!
