Not exactly level 50. Some classes get their job advance sooner. I think the only class that get its job advance after level 50 is the Monk at level 60. Also, it's possible that the shop will never come. It's been quite a lot of months since we never heard any new from Colino, after all.
@Metallorry: I just got that bug myself. The game doesn't have any restart option, so if you don't want to lose all your progress (except exp), refresh the page.
Pro-tip: For fast Valve upgrading, press Tab until a yellow square appears on the Valve you want to upgrade, then Hold Space. Thought I personally didn't feel any difference beetween valves level 300 and valves level 1000.
I let the game on to see how far I could reach. Then I got caught into another game and forgot this was on. Before I realized it, I reached 97 millions :O
I prefer using MsPaint than this. No eraser, no fill-in color, nothing to make beautiful curved lines... If you can't make a tool better than the base of image editting, then don't make one. You lack essential features.
Woah. I thought I lost all my character, the game loaded and asked me to create a new character. I refreshed before creating one and I'm back with my monk. Phew
somewhere = invisible threadmill. Yup, they run on an invisible threadmill until a monster is curious ennough to get closer and identify what the heck you are doing.
@penguin765: I did some search for you. The music is almost the same as the one in "No time to die", probably got modified a bit through some music editting program. The music was made by someone of Newgrounds, who named it "Three Gear". The music itself is a remix of the music "Track 1" on the Snes game "Top Gear".
