All stuff unlocked. There is a bug : page 5, the last weapon. Noticed it's unlocked "!" but there is still a "?".
The lag is annoying but I enjoyed the game.
I expected better combo (4 four ninja turtles are bad because of special set and 0 range weapon).
TIPS :
Good special set : double shot, blocking attacks, not rebound, attract fish
Bad special set : double damage, traps, heal
Good team :
1st tank (blocking attack, 2 life 1 stamina/level)
2nd tank/dps (not rebound, 1 life 1 force 1 stamina/level)
3th range/dps (double shot, 2 force 1 stamina/level)
4th range/dps (double shot, 2 force 1 stamina/level)
Cause range/double shot is STRONG.
page 1-2 = map 1 ; special 20%
page 3-4 = map 2 ; special 30%
page 5-6 = map 3 ; special 40%
page 7-8 = map 4 ; special 50%
Special set is useless until 40-50%. Focus on items without special (like nyan cat 22 life + anothers items, strong early)
Final boss : the final kitty is squishy. And I expected special items drop on the 3 boss, but no.
