Thank you so much for playing the game.
As for the problem where monsters do not always match their info page, I’d really like to know more about it if you can provide more details, because I tested the game many, many times and never encountered this issue myself.
As for the skip button and mapping it to the Enter key, the game was designed to be fully playable using only the mouse. So honestly, I neither mapped anything to the keyboard nor tested keyboard controls.
Regarding the undo feature, there is no direct undo command in the game. That was intentional, to emphasize the consequences of a wrong placement. However, before Level 5, you can do something similar to biological control in real life, where you place a monster to eliminate another monster and free up space for a different one. From Level 5 onward, you unlock the expel ability, which lets you expel a certain number of monsters from the shelter per level.
Thank you so much again for trying out the game and for the feedback!
