Item description:

Megablock Survival is a simple survival map consisting of twelve 16x16 islands floating in the sky, each with their own theme. There are challenges to complete (and more will be added as I develop the map more) which give you rewards. Cube Points, which can be found around the islands in hidden chests, are used in 3 shops hidden around the map.
The rules and some general information about the map is located in the spawn area. On multiplayer, you will probably spawn outside the spawn area within a fenced area. Climb up the ladder and drop down the hole in the ceiling to enter the spawn area. Press the button in the spawn area labeled "Press to begin loading map" to, well, begin loading the map.
Megablock Survival has the unique feature of being 100% replayable, with added benefits. The way the map loading works is by cloning the islands located near the spawn room up to their correct places in the sky. You can go back to the spawn by pressing the button on the Grass Island, then pressing the "Back to Spawn" button in the Control Room. Then, return to the map loading button and insert 32 Cube Points into the dropper located there to reset the map, which will delete and then rebuild all of the islands.
Intentionally, only the islands themselves are cloned, and not the airspace around the islands, so paths to other islands and any items stored off of the islands themselves will remain when the map is reloaded. Therefore, if you want to keep items between map loads, either keep them in your inventory or in chests away from the islands.
There are three separate sets of armor found in the map: the Dungeon Set, the Machine Set, and the Guardian Set, from worst to best in that order. In the three shops hidden around the map, unique items and potions can be bought.
Thanks for playing and please report any bugs, problems, or suggestions for map redesign in the comments.
