Nova drift does things very nicely, and it is still on early access. Here is the quick run down as there is not much to say about the game, but at the same time a lot to do in it.
In nova drift, you take control of a spaceship and your goal is to survive by avoiding enemies, anomalies, asteroids, obstacles, and the sort. Every time you level up you are prompted with a pool of abilities to choose from. Each ability you choose can be further upgraded to a total level 3, level 2 having 2 options to choose from. Choosing one option locks the other one out forever.
In addition to upgrades, you can also choose from a variety of weapons, bodies, and shields. You can also choose to forego a shield for the added benefit of a stronger hull.
There are a lot of abilities and equipment to unlock as you rank up by simply playing the game and getting as far as possible on each playthrough. Try out a variety of combinations to see what works best for you. Some upgrades feel like an afterthought. As you upgrade your abilities more, you are introduced with drawbacks. Some drawbacks are easy to live with, and can be counteracted with picking up abilities to make up for them. Some drawbacks however are so severe that the certain upgrade would simply make no sense to pick up. The only way to find out what works best for you is to pick something up at least once.
If none of the upgrades available in the limited amount pool of upgrades does it for you, you can re-roll for a new pool. You pick up re-rolls by defeating high ticket items.
