Drags you in from the get go, super addictive! But fallout from here is quite steep. Got bored in about 4 hours of playthrough and uninstalled. Never looked back. A mindless roguelite grinder for bullet-hell lovers.

DON'T RECOMMEND!

Takes about 10 hours to get achievements if you don't leave your game running.

For what it is it's solid. Controller support is spotty but it's an auto shooter so :shrug:.
I bought the game on deep discount. I DID expect something a little more fleshed out but the game play is fairly hollow. You're essentially going to use the same 3 weapons and same character every round for the best performance, but as far as 10 hours of gameplay is concerned... you'll enjoy it and you'll 100% the game. Sounds like a win to me.
