Really clever Metroidvania with a unique style and really neat tools. Each area of the map is a joy to explore and figure out.

A warning though: I don't recommend delving into the post-game.
The game got really aimless for me at this point especially since it doesn't differentiate between puzzles that are needed for progression and puzzles that are really difficult secrets for the community to figure out. That said if you really enjoy some cryptic puzzles à la FEZ then go ahead, there's plenty to do.

It's great to finally see a indie soulslike that is very well made and gets some hype on release. The passion that went into this game is obvious every step of the way, from the humor, the references and the character designs. The gameplay isn't groundbreaking, but it feels great. The best part of this game is easily the visual design especially with all the creative uses of trash. The cavalry-lobster with the cup-lid and straw combo as a rapier was a definitive highlight. The level design was also neat, it opens up quite a lot thanks to movement techniques like a glide and a grappling hook.

There are some minor flaws though. Enemy variety is a little lacking. While the shell system is really cool, it is also quite easily broken with shell-insurance. Once you get a good shell with a lot of health you can get it back at every checkpoint for your back AND your hammer. This means that after one third of the game you rarely have to switch your shell on the fly and many enemies get trivialised.
The story also ends up on a rather confused note. It deals with a lot of interesting ideas like capitalism, complacency and rage against the system but imo it didn't manage to tie those together in the end.

All in all really cool soulslike, the industry needs more games like this.
