This actually really cool! Only downside if you don't have a gun you can't do anything! Also cool that you just need to destroy the core and that all other parts can be added to your ship.
More types of weapons would be really cool, as well as upgrading existing ones. (drag for example a booster onto one of your boosters to upgrade it to a next level). In the inventory aswell, drag em onto each other to create a next tier version. Then that one can be dragged onto an upgraded version of your ship. This has so much potential! :)
