Had a really good time on this game with a friend of mine !
Cute graphics, nice gameplay, learned in 5 seconds : perfect : D.
Only complaints : not having 1 ball color / player is a little confusing at first. Also : some boss battles are reealy long. The succubus and the final boss took us much more time than any other. Touching them just once can take long, and do so little damage : ).
In two player mode, it doesn't matter which ball you hit. The only rule is that, if some ball is lost, both players get damaged. That's why we discarded having two different ball colors.
The length of boss battles is really a matter of strategy. There are endless regular enemies, so there are endless power ups, and some power ups make high damage. Also, you can hit bosses with their own projectiles. Xasmine battle has a trick: hit her with your attack AFTER she tries to hit you with the scythe, just a matter of timing. And Lord Vanik is the final boss, so... anyway, hit him with his own bats and you're done with the first part.
Thanks a lot for playing!
