Very fun, I would like a setting you could toggle to dash towards where you are moving instead of the cursor and make it where you don't dash when you pick an upgrade. In the game I would make it where the cursor hides when in game and shows when selecting upgrades so you don't have both the mouse cursor and target cursor, It got a little choppy at the start of later waves but would mellow out. when it started I tried to use left click to select an upgrade so maybe a little graphic showing to use Right click. I could have got unlucky but if you don't have one a health regeneration upgrade would be really useful, that is my feedback, really fun and high ratings from me!
