Very fun to play! I like your personal twist to the formula, it adds some spice to the endless runner genre! 😁
Having to throw obstacles at yourself with a time limit is a nice and original challenge, it scales difficulty progressively in a nice and organic way, well done!
I've missed a press-sensitive jump (pressing the jump key more time makes you jump higher) but I guess that dropping down was your way to fix the problem. Just being a bit picky here, the game's quite fine 😛
Good job!
