I have to say it's rage inducing in a good way, I ended up saying like "give me a platform, c'mon give me a platform!!!" and then leaping into the abyss to just die, haha it was hilarious, it seriously left a smile on my face!
I do agree with the first comment, the RNG can mess up your run so bad, even if you pay attention and you do everything right if you don't get a platform, you're dead. RNG punishes you in a cheap way.
I'd also fix is the fact that if you're in the air (jumping) the death collider at the top of the screen shouldn't kill you, that way you give the player a last chance, a "leap or die" option, otherwise if they don't have a platform below they're dead because if they fall they die and if they jump they get killed by the collider. This way you'll at least give them the last chance of reaching a further platform.
It's simple but it was really fun for a couple of minutes. Good job!
