A dissapointment
I have a lot of complaints for this game.
Firstly, lack of breaks in between rounds, this is extremely annoying if you're on 1% health and have only 3750 cash (real situation for me), and with 250 more cash you could get yourself a second automated turret, but no, because the next round will be far too long away and you will inevitebly die. I think you should be able to pause the game when you like and buy stuff, not wait for it to come up.
Secondly, all of the weapons between sledge rounds and the lasers are rubbish! They all have a really low rate of fire, and thus you're better off just sticking to the default weapons and then suddenly making the pricey jump to the lasers. Fix it.
Thirdly, the automated turrets can't be upgraded enough. Sure, there's the visibility, but there's only 2 settings for the actual turrets. That's there, or not there, with a standard laser ammo for "there". And that means they're pricey. You should start with just sledge rounds for them and then upgrade, with the upgrades costing less than controllable turrets because you can't control them. For example, I might want my turrets with rockets to easily cause a lot of damage to close up asteroids, or with rapid fire rounds to help hit them from distance. Or even make them switch between them as they get closer. Yeah, do the switch between thing in the next game. That would be awesome. Anyway, so make the turrets upgradable instead of just awesome as standard. That plus being able to call the upgrade menu whenever you like, and adding more rapid fire weapons, and that will be awesome.
So, please fix the above things, and this will be epic. It will be going straight to my favourites list.
