I think the bass needs a bit more variations on both tracks, it's better on the second one though, it's more than a little static with that upbeat thing (which has already been done to death). Overall I like it though, sounds NES-inspired and I like that. For the 1st track I'd suggest a little more work on the mix, there's one sound on there that dominates too much when it enters. The second one doesn't have as much interest in the lines but the overall tonality I like better. If you put some vocals over this and "dirtied" it up a bit it could be a dead ringer for Postal Service. One-and-a-half thumbs up!!
