Unreasonable bouts of lag + difficult to gauge jumping mechanics in a platformer is a recipe for a frustrating experience, and that's the cocktail we have at the moment, regrettably. Until both of these issues are addressed, the game unfortunately is unplayable.
Excited as I was to see this, I'm afraid Frantic 3 the worst addition to the series insofar -1) Boss timers make me feel upgrading my weapons is a waste, as I wasn't killing bosses faster than their timer killed themselves. 2) Restart Level button please. 3) Bosses are generic looking. The thrill of previous installments was seeing a massive beast of a ship come at you, toting tons of guns, making you think "Which one am I going to shoot off first?" That level of interactivity is absent here. 4) No in game achievements? 5) Overall level design pales in comparison to previous games. The "campaign" feel of the game is gone...now it's just a grindfest of upgrading my weapons to the point I'm able to handle the next level suitably. 6) The music, save for the final area, does not have the same fast-paced, dare I say "frantic" feel to it. 7) Boss drops are incredibly disappointing. Drops in general are boring.
