1. Yes you could have a money based system. All it requires is a value in which you add, store & remove money from.
2. You mean the naval combat mini-game? Hmm... I believe it would be possible, but might be better off waiting until the next release of Visionaire Studio as keyboard control should be better supported due to fully integrated controller support. The cannon / projectile part is somewhat trickier as we don't have an instance create / destroy system, so you would have to manually create some animations for cannon balls (projectiles, whatever) that can be recycled, then you would have to snap their position to the position of your ship character & then check the current direction of your ship to calculate which angle they should travel at when you fire them, then you would need to run a loop to determine if their position + radius value comes into contact with another ship to impact or if distance traveled without contact equals or is greater than something to miss & disintegrate or something. In other words it's all quite complicated. A mini-game like this would be easy to make in Game Maker because it supports instance create & destroy & has collision detection & destruction action options already built into the engine. VS is a point & click engine so it didn't really need any of those features.
