Thanks for the feedback! Sorry about the lack of instruction, it was just a lack of time thing :) I was hoping to have a storyline + tutorial in game.
I've updated the game page now and will paste the relevant info here;
"Can be played alone or with up to 4 friends online multiplayer
Explore each zone to discover any mechs which will help you traverse the area.
Reach the green circles to progress to the next zone
There are 5 zones; Bunker, City, Wasteland, Ocean, & Sandbox
It ended up being more of a tech demo due to time constraints but please enjoy!"
There are also some more "spoilery" details on the game page about which mech is in which zone and what you are supposed to do where
