I applaud you for making a platformer that controls crisply with precision. You also gave me a chance to get used to the controls before giving me something too challenging.
I assume you're aware that the guy needs a climbing animation when going up ladders, more of a detail really.
I noticed that right after my guy died from hitting a trap I would respawn in the same area but with the trap used up. I could keep on going as if nothing had happened. That defeats the purpose of the trap.
I also noticed that I wasn't able to tell if a switch was going to be beneficial or if it would be a trap. I just started assuming most were traps since traps kill you instantly.
