Here is the download place
★Axfc UpLoader Neon (4~6MB) -Ne_107457.zip- (the keyword to download is '"inui")
the test file contains only a few movement: basic move, zoom, dash, jump... ... however quit promising.
Attention! I've tested the game, in windows 7 it is un activatable even with apploc japanese, the only way I successfully activated the game is to change the "non unicode program language" to Japanese.
