Exit the Gungeon isn't as good as Enter the Gungeon, but you shouldn't expect it to be. It's a fun spinoff that costs less and is meant to be a shorter experience. I enjoy this game and I think Enter the Gungeon enjoyers might like it to if they give it a chance.

I think it's a pretty decent game.

I see a lot of hates cause it's something new and mobile-ish, but Dodge Roll tried something new with their own assets, and they're pretty fun. Especially, if you get it when it's on sale, it's dirt cheap. So...

This game feels a lot more "random" than EtG
get to floor 2 and have a item for 350 coin in the shop even if you haven't spent a single coin and perfected every boss up to that point you can't afford it
get a quest for a npc item complete 2 runs without getting a single minigame for a "chance" to get the item
its a fun little timewaster game especially if you enjoy achievement hunting
but the content of this game is only available by endless grinding fueled by rng
you see the content when the game wants you to regardless of how good you're at the game
this is reaffirmed by the lack of updates from the devs compared to EtG
having to rewatch the same animations prior to fighting the dragun and being forced to defeat the octopus risking your entire run over and over again despite the lack of reward really sets it in
there could've been something really great here but it's obvious that this is the same game with less complexity, meaning, or purpose
