update broke the game? mobs have about 10 times the movespeed than the video in the comments. unplayable. also invulnerable when hit upgrade does nothing. that already seems to be active at game start? or the upgrade is meant to extend that duration and doesnt.
Hi! I checked the game in several browsers, and did not notice any problems with the speed of mobs.Perhaps I can figure out the problem if I know the configuration of your computer, as well as the browser in which you run the game.
The Invulnerable upgrade significantly increases the invulnerability time after taking damage.
