Hello! The "w" key not being able to climb is a bug because it doesn't properly bind the key, this is my fault and I'm sorry, the ladders are scripted in a way that an "up" press wouldn't take you up, there's something called a "ladder press" and i didn't make it so that "W" simulates a ladder press, i made it so that it simulates an "up" press and as we know that doesn't properly climb ladders. I'm releasing 0.48 sometime today or tomorrow and i would recommend joining the discord for better interaction but anyway, thank you for playing! I'm an indie dev and coded this game entirely on my own so sorry about the bugs and glitches.
Discord : https://discord.gg/Ccn2MzCX in the discord you can directly contribute to updates and help with ideas for levels (each update adds 3 new levels)
edit: Sorry i missed out the top down zelda style movement level, that is a bug aswell similar to the ladder bug and patch will release for version 0.48 (currently 0.40) which fixes this stuff.
