R for auto restart and auto pause option for when mouse leaves window. Far too many times I have taken damage because mouse left the edge of screen so ship doesn't move and gets hit
Very annoying you cant move items about in your backpack. I dont like having gaps between items and when new items comes in you dont know where they've gone too.
enemies tend to have high hp/armour on vitals eg body/head. A much easier way is to disable enemy with leg attacks for dual wielders and arm attacks for enemy with single weapon. Then just keep defending and wait for them to bleed to death.
Sharks and humans swim through solid rock. A huge problem when your task is to kill all skuba divers and they seek refuge in solid rock where you cant get them.
Bug where ship is off the screen and you cant cancel the mission to end the day, only way out is to die. Also, when facing final boss, entering the portal from the top is instant death, you come out the way you went in and you cant steer fast enough to avoid dying. You should at least be able to avoid instant death regardless the direction you went it
Rogues don't even have priority, their skills all fire when ready and do not block each other. Sap will always fire if there is a mob and it is off CD.
There needs to be a major upgrade in the screen movements. If you kill last monster and knock it out of the screen, you cant scroll over to collect the gold. Major losses esp on missions when there's just 2 big monsters to kill.
Platinum challenge on battle VII is not possible. You have no move command and the Ogre B refuses to move for some reason or is trapped by some invisible barrier. So after you kill the other monsters there's no way to kill the final ogre :(
A small point, all upgrades cost 3 stars but the first 5 missions gives 1 star each so if you max them out then for the rest of the story till you finish, you'll always end up with 2 spare stars, not quite enough for another upgrade which is damned frustrating.
