In spite of it all, I'm sill happier with a developer who maintains involvement in his project than a game with a develop who promises a lot and disappears for months.
Does this game run off-line? Sometimes I come back to see all fuel cells depleted; other times it takes up where I left off. This game is such a CPU and memory hog that I hate to leave it running in the background when I'm trying to do other things.
It seems I spend at least half my time waiting. Waiting for gold or gems or other prizes and items to process, waiting for the ship to move, waiting for bosses to appear, waiting for curtain to open or close. This might have been a good side-shooter game, but the inter-game content is a huge drag.
Any game with unresolved glitches reported over three years ago deserves no more than one star. It certainly deserves no badge if the developer makes no effort at game-maintenance.
I hate the sort of game where you are expected to know what to do without any guidance. Of course we are all born knowing the recipe for werewolf sleeping potion.
I remember the tanks in the other Bubble Tank games being more agile and responsive. They also carried momentum into new arenas. Is it intentional that a tank comes to a complete stop, leaving it a sitting duck, when entering a new arena?
