Hi! Thank you for the review!
I didn't notice it was missing, but Q-E keys are the intended ways to scroll the inventory, while 1-2-3-4-5 and the mouse wheel are alternatives. I included Q-E in our description, thank you!
We might've ran into the good old developer bias, where we got experienced with the game, and set the AI a tad bit too high. Not to worry, there's a mechanic that periodically deals damage to a dominant player's monsters, although I did notice that some monsters can tank these hits :D
Glad you enjoyed our creation! We'll make some adjustments after the scoring is finished for sure!
