Thanks!
Yeah, I've heard a lot of people had troubles with wall running, I've been testing out how it works in other games and I'll update mine to make it feel more intuitive.
As for the platforms out of reach you are the first one I hear that from. In the tutorial I mentioned that if you hold space you jump slightly farther, so maybe that's it? There are also some harder jumps, but those are in the second level.
It is possible to slide under all obstacles in a single slide, but yeah, I've seen people having a bit of trouble at first with this .
I think it being first person makes some distances harder to judge.
Glad you enjoyed the game!
And yeah, that was the intention of that little cutscene with the guy dying, thanks for mentioning it!
