A very nice rendition! For some reason, i kinda wish the main instrument and counter melody at the phrases like :12 were kinda switched, but it may actually sound worse, I dunno. The counter melody is just a more prominent and better instrument to me; this is all personal preference.
The only other part that seems like it could use some change is 1:13, where the bass is so low and only the melody plays that it feels both empty and hard to actually catch the bass's notes. I kinda wish the bass changed during that part, keeping the harmony and chords moving, but I don't think the original song did that then.
Other than that, great work. I love the way the counter melody creeps in at 1:09, really captures the original essence. I caught no wrong notes, the pace is great, I truly could visualize this being an 8-bit Golden Sun battle scene. Golden Sun was the first RPG I played where I really understood how the mechanics and numbers worked (was too young for that when I first played Pokemon). Love finding others who do as well.
There's a very good chance I will give this song another whack sometime in th future~ I'm sure I can improve it! Perhaps I'll give some of your feedback a try while I'm at it, see how it sounds in realtime.
Please contact me if you would like to use this in a project. We can discuss the details.
