I'm not a big fan of Adventurer 2 and 3. The 1st one is very fun to play, with a lot of possibility to play and avoid some powerups. The 2nd and 3rd feels just hard.
Fun fact: I had many lvls, they disappeared because I changed my name. One day I was shocked I has no lvl anymore so i made Adventurer, it was one of my first (not really like, first making a lvl in the new accident account) level to be made an the next day... I was even shocked by me getting in eternal day!
