Hello, I played the Endless Bossmode Arcade Mode to Level 21 and stopped there because I only wanted to get the said achievement. I quit by selecting "Endless Launch" (rather confusing name for ending the mode I find) and I got all the cash but no achievement. See screenshot of my trophies. Game version: v1.01H...

According to the wiki, it seems that this is the only one I missed. Thanks for help.

How to find the version of Boss 101 you are using? It's on the main screen options page at the bottom left! Build Updated 1.02B Minor Fix - adjusted the firing button and trigger in Rob's Adventure to function the same. [/list...

Or do you just go on randomly generating bosses?

So, I think that I met with an error/bug - two minigames, Mazard and Rob's Adventure have almost the same leaderboard. Is there any way to fix that? I really would like to get achievement for Mazard but because it share somehow the same leaderboard as Rob's Adventure, the score is too high to achive....
