Hi guys, I am Picman from China.
Spiker is an online platform for I Wanna players to make & share & play maps. It's easy to use, with a pretty UI.
The newest version is v1.03 α, which includes:
1.The workshop for you to make maps. Like RMJ or JTool, it has different kinds of blocks & spikes, two kinds of water, walljumps, +1 jump and platform. You can toggle the death, maskbox, trail and grid on/off. What is more, currently there are 4 different SKINs for you to choose, which are "NONE", "DOUBLECOLOR", "LINE" and "CLASSIC1". By changing their colors, you will get pretty cool effects. After logging in and changing the title you can publish your map, but before you complete, you will have to clear the map yourself.
3.Downloaded Maps (You can play them offline).
