Wow, the only thing I would have to say is that there is an issue with the first jump. I thought it was a puzzle when in reality it was just a glitch. I was able to solve the glitch by reseting the player's spawn point. But all in all this game has a huge potential and I really wanna see a story for this game. I wanna know what happened before or what our enemy is. This could turn out to be the next portal 2 if development goes futher! All in all I really enjoyed this game!
That's no small praise, and the sentiment is appreciated even if it is a bit of an exaggeration! :)
I think the reason you had trouble with the first jump is that it only works if you press A and push the stick forward at the same time. The button hint should be clearer in that regard.
And I might make a small patch later this weekend to make the climb work with only A. Because you are not the only one to have trouble there.
Thanks for playing!
