Awesome pacing, and apart from some tiny visual quirks, it looks really good.
One critique is that there's only one secret and it's super easy to find. It would be nice to have some secret hunting. Resources were plentiful in this map, which felt great. It would be cooler to have those resources a bit more restricted, and have a few more secrets to justify it.
Still, the map gets 5 stars for being good fun and doing the 1024 limitation justice. A lot of good gameplay gets crammed into a small space. Great job.
I'll definitely be giving this another few plays.
