Thanks for the feedback, I'm glad you liked it :)
You found the bug (feature?), didn't have time to fix the kick through walls ^^
You are right about the jump but because of the heavily crowded places, sometimes you could get stuck so I though about leaving the jump just in case
You are also right about the enemy detection which is currently a sphere, that's why they saw you at a different level.
Thanks again, glad you had fun!
