This has a nice old school vibe to it. It definitely works.
I think what I would adjust is some of the volumes, panning, and overall sense of space with the music, giving the vertical arrangement more balance (i.e. basses, mids, and trebles). Towards the end, the trebles get a little harsh and grating, like maybe it would be good to EQ them down.
As Pixcele mentioned, they started to mash together a bit. I can kind of hear what you're going for with the ensemble effect, but I think to really bring out what you're after, I'd try to adjust the volumes of things.
The Spyro soundtrack is one I really like from that era, and it still definitely achieves a lot more balance of the sound on the ears, a nice sense of space, and softening things up with reverb:
Overall, your composition is quite good and works really well to convey that old school game vibe. I think the balance in sound, and mitigating some of the harshness is something I'd work at a bit.
I hope this helps, I definitely like where you're going with your composition!
