Hey there yes Game maker rocking these days love the stuff you implemented with it!
I should have those platform fixed the best way I can it still dosen't follow the x but can walk and jump without getting stun in them now(I was thinking about removing those but I grew attached to those ahah).
I'm still thinking on how to define what's happening at the start of the game that the "bomb" is about to explode and give the player the urgency to survive. Glad you enjoyed it and I would love to hear if you make it to the doors of the ancient city!
