At first game starts pretty easy. It provides a lot of fun, until specific type of drones appear. Hitscanners. It is really hard to avoid their shots and their appearance means to you will simply loose health. From this point on game is really hard. This is a shame, because game is actually good. Great controls, maze like levels, awesome weapons.
This is not an FTL clone. Sadly, because FTL is an easy to learn game but hard to master. With FTL you simply fire your Flak Mark I at the enemy ship to lower the shields and use a fire beam to fry them. Or perhaps board their ship and kill everyone in sight. In STTE first you have to make sure that you have special ammunition. But if you do not have ammunition, you can always scrap some stuff to get that ammunition. But you might not have enough storage for that ammunition, so you have expand your storage by building storage container. And if you do not have specific scrap to buy that storage container, you can of course scrap other stuff. Do you see where I am getting with this? This is not a space combat simulation, this is some economics game with some combat flavors. To put it simply, bean counter simulator.
