Ok, it's a small runner with adequate gameplay, but I miss some kind of traps and interesting obstacalse, as most of the time I can run and do nothing. Eventually, I bored. 

Cool game, although I felt like there was a lot of downtime when I wasn't killing anything and was just running. I like the idea, though, and the art as well! Nice job :)

Also, I ran into a bug when I hit a rock:

FATAL ERROR in
action number 1
of Draw Event
for object oGod:
Unable to find any instance for object index '7' name 'oPlayer'
at gml_Object_oGod_Draw_64
############################################################################################

stack frame is
gml_Object_oGod_Draw_64 (line -1)

I really like the art and effects, and the gameplay is fun and straight-to-the point :)

I think respawning on the level you died at would be a good idea, since the first track is a bit long.

And also, you should consider making your game window's size changable. On my monitor, ithe game was really small and I could barely make anything out. In game maker studio 2, it's as simple as ticking a box in the settings

The first stage is a bit too long, it almost ruined my impression of the design variety.
