I managed to play it in another browser, the feel when we defeat the enemies is great. When dealing with an enemy type a second time the “mechanic intro” sequence could be faster I am talking about the screen where it gives you instructions and there is a timer since we have seen it already.
QTEs are well implemented, its a shame I got so many problems playing this game, when I got to the 7th floor I got spawnkilled. Overall, its fun.
