I love the concept of this game and find it very addictive. Finished it (felt it was very short and very scarce availability of power-ups, both in quantity and diversity) and was looking forward for the survival mode.
But after a few (many!) tries, I keep dying like an amateur! I don't get it! How do you survive this time limit? Killing baddies, picking up the orbs... but very small increase of time... and in result, I think I can't survive more than 30s or something! Any tips for that piece of #"#%$#"#?!
PS: I can play "Waves" until I get tired of staring at the screen, but this survival mode of "Ion Assault" is making me feel like if I am playing Ghost n' Goblins!
