just a warning go damage build defense build is not balanced in this game and will get you know where unless you want a multiple day grind then choose defense over offense
i started the game up before pressing level 1 i pressed the blacksmith saw i had 0 gold no surprise there hit back the screen went black but i could still see the special mouse thingand can move it around i have a mac os x for a cpu
game has a bug when i press start game the screen turns blue and nothing happens i have a mac ox X for my cpu (up vote so the creator can see this and fix the bug)
im with nomological on the bug with unable to get past the difficulty screen im playing on a mac OS X version 10.7.5 if that provides help for fixing the bug =)
alright i found all the endings
SPOILERS
1st ending go right climb up mountain then jump to the left the sparkles indicate invisible platforms
2nd ending go past the spikes press down on the cpu thing and let the ghost murder you
3rd ending the hole with the hot stuff coming out time it right so you dont hit it and fall in
4th ending use your broken space ship to go into the cave on the left and solve the puzzle
5th ending go right untill the cave with spikes falling down instead of going through the spikes climb the mountain and head right then fall down
6th ending: go right past the falling spikes get the thing on the cpu and return to the ship
hopefully this helped =p
