Definitely feels like Etrian Odyssey, right down to the TPKs! I really like the information you present about objects in the world as you approach them and the strafe selection at the start of the game is also great. Everything feels really polished menu wise as well. It would be nice to be able to use the selected ability in combat without clicking on it again though. I also didn't really know what to buy the first time through but apparently ammo is always good to have and apparently so are the kits to revive. All in all, great game but definitely difficult depending on what enemies you run in to and how often you miss.
Just an edit to say that I figured out you can just use the spacebar to select everything and that makes the combat selection easier and faster. My brain defaults to mouse still.
