This was a really fun, chill Metroidvania with local co-op. Played this to 100% with my wife. One complaint I do have, is the game provides the typical, "You are about to enter the end game and won't be able to explore" screen. However, the first one is A LIE and it's so dumb. This isn't like a hardcore game, so why make a fake screen? We went and got all of the collectibles. Once you accept "going to the end game" you get fast travel, which would have made getting all of the collectibles 1000 times easier.
Then, you do like 3 things that you basically teleport to with fast travel and then get a screen that says the same thing, but adds, "We mean it this time."
Bad DESIGN there.
