i played through a dozen times and was never able to climb up a ladder.
with a bug like that i can't really justify spending any more time on this.
also i couldn't find a key for attacking the skeletons.
also, upgrades only applying to random powerups and not getting upgrade base statisitcs... really sucks and feels like shitty progression.
see that rating? now know that i'll be rating this submission with that same score every day. as well as a bunch of friends, all of whom have even more voting power than me.
