Coinciding with the launch of Super Mario 3D Land, indie developer Robot<3Kitty (IGF 2011 finalist Neverdaunt:8bit) has released an alpha version of Tiny Plumbers, which looks an awful lot like Nintendo's platformer, right down to its power-ups and princesses.

But while the Windows/Mac game still has you jumping on enemies' heads like Mario, the graphics here are "ultra low resolution" and much bloodier. This is also a procedurally generated game with support for splitscreen and online multiplayer.

Robot<3Kitty is working on adding more features, levels, and princesses, and has made the game available for pre-purchase for those of you who want to support Tiny Plumbers' development and get early access, wallpapers, concept art, and other cool stuff.
