Thank you for the feedback! And i agree with you completely.
As for the polish text I actually messed up there. The demo was supposed to end after using the sewer access card but i forgot to set the switches back after testing, so the game keeps going. The med room and the vent interactions weren't supposed to be in the final demo.
I will fix this as soon as possible.
And of course i agree on the intro part and the sprinting mechanic. There's a lot of things i would do differently today, one of them being a better engine of course.
I may revive my patreon if there's enough interest in continuing the game.
