I like it. It's pretty simple and has some cool moments behind it. Usually I find that if it's electronic and it's composition heavy I don't think people mind too much if it goes in the video game genre. I do that at least and no one has said anything. It still does give a bit of a 90's feel, but you still make it your unique style. I can see this stuff being used for some Luigi's Mansion stuff.
Starting with the mixing first. It's not bad, but it does seem held back at times. Especially at 00:49. The chorus synths could stick out a bit more. However, you still make sure that what is telling the theme the most is heard. I like the transitioning arpeggios.
The composition is where you still shine, and I like that. It really helps to have both mixing and composition, but I find in my opinion a piece that's mixed really well but is lacking in composition is fun for a bit but isn't as entertaining as something that doesn't have the best mixing but is really fun to listen to. But like I said, it helps to have both nailed down. Otherwise it's like cold pizza that's three days old. Not as good as when it's fresh.
Back to your composition though, I like what I hear. It's like a dark cartoon (or like Luigi's Mansion as I've said earlier). It doesn't quite stick out as something that makes me want to download it and listen to it while I'm doing homework though *sad face*, but you're on your way. You use the simple chord changes quite effectively, and then you break it up a bit to keep it fresh at 00:49. The build up at 01:27 is a nice touch.
It could use work, but I wouldn't touch it (doesn't make sense but oh well). It's nifty and I look forward to seeing more of your work. While the synths you're using sound vintage, your style isn't.
