The blind jumps actually aren't as blind as they initially seem, at least in base Spelunky. You can always hold the down direction to move the camera downward a bit, letting you see what's coming before you jump down.
i know, i finished it last week , ah six days ago it says but from what i found you dont always see the bottom even when looking down. Its an awesome engine that could spawn several platformers of different style with responive versatile mechanics/controls imo. I just feel this specific game would benefit from like at least 15 to at most 30 designed consistent levels on top of the hi score chaser random generator.
It might be a lot to ask for a 3 euro game lol but im not really asking, i just think it would make the thing total GOTY material, i enjoyed it anyway, great stuff, these guys got skills lol
