It brings me back to Castlevania. I like that synth organ kinda like a church organ. At 20 seconds where it comes in with that bass is really nice. I like the deepness of it. The composition is new to me since I haven't worked with that type of genre or at least not as much as I used to but I like how video game it sounds. At 1:49 or like the main chorus of this song I felt like the drums were a bit too high. The kick especially had too much bass and release on it aside from the major boost in gains. It could do with some compression or some processing to help find that right tone. You can even use an equalizer which would help balance your high pass and low pass giving it a more crisp kick drum. You also have the option of skipping processing and simply adding some noise background to give it that really nice 8bit kick effect. Aside from percussion and lack of equalization I think you have something going on here. You seem to have a keen mind for making compositions which is a plus and like I said I'm not big on this sort of sound but you're managing it quite nicely. Work on your percussion and mixing/mastering and you should be fine. Also along the way you'll learn new stuff which will help you progress even further within the world of sound.
Some other advice for the future would be to maximize your understanding of oscillators. They are the main key for making video game music. 4/5 for me Keep Up!
