Confusing puzzles that lie to you and yes there's alot and this game has alot of keycodes you'll be spending most of the time handling and guessing keycodes then shooting nurses. Yes it's that tedious.

For bugs, oh boy there's alot. There's your inventory that sometimes straight up lose your items including key items and ammo when you have a full inventory.
Your partner sometimes can't go through doors unless you close and open again.

There's even bugs when you simply open key doors without solving the puzzle.
There's also items you get that turn out to be useless in the end cause I've beat the game so you just holding on to them for nothing.

Unlike the eTIRUe games this one doesn't have unlockables or new game plus or anything it's just one sitting and that's it. Which pretty much makes this game the most frustrating experience I've played.

Of all the eTIRUe games I've played. This one is just not it. Sorry.
But you know the usual, the devs will probably fix it and add new things. I hope so at least.

EDIT: Updates has arrived and mostly bugs fixed. Thanks for doing this devs.
