yeah the game is pretty challenging. the only way that i could find to beat it was with the ghost sniper.
best max tank i think
btw to get bft, you have to get a max tank then go to 3 bubbles and he will appear. beat him to get invitank
the reason theres no badges yet is because you either love this game or hate it.
some people just dont find joy in moving your arrow every 2 seconds just barely a degree.
other people love it because of the constant killing and upgrading for killling.
