Epic maps.
I liked blocko raceway, but I really wish it was more of a raceway instead of some deathrace thing.
For oasis, my only requests:
Bigger. You can enter the repeating of the map within 30 seconds. Pretty dull as of now.
Enter-able pyramids? Maybe just a single tomb/treasure room inside, nothing major.
Easter eggs. You know "Egyptia"? It's supposed to have some sort of heaven place. Something like that would be kewl.
