I now have a playable version of my game, for those of you out there who have Linux.

https://www.dropbox.com/s/z9tlr3gjqdzjpym/Beneath%20the%20Mushroom-Beta.tar.gz

Controls and stuff:

Select the circle thingy with left mouse button, control it with right mouse button.

Your goal is to absorb/collect/consume all the resources.

In the top-left corner you can see the selected circles energy amount.

The 3 buttons in the top-left corner are actions you can assign to the circle thingy.

You can see each actions cost. (first action is nothing, second action is dig thru wall, third action is dig thru enemy mushroom)

It costs energy to spread, but going on a white area is free.

The mushroom turns resources into energy and gives the circle thingys energy eventually.

Finally, you can restart the level at any time using the spinny arrow button.

Im probably gonna submit this after some feedback, thanks!
