Level is another airline company in the budget options. You get the minimum possible and pay for all the extras.
Overall is not a bad option, if you know that you are traveling on a budget. If you expect out of the park service then choose another airline.
The check in process is odd, since they just show up 3 or 4 hr prior of departure, so if you come in from a connecting flight you will be stuck with the bags until the open.
