I'm new to hedgewars, but I think it's a really great implementation of this game concept!
My one problem though (I'm not sure if I'm missing something) is that I can't use air strike or cake. When I right click for the weapons menu, and then left click on either of these weapons, the weapons menu closes as though my selection was successful, but the hedgehog is still holding the previous tool/weapon. If I use the F keys (ie, F6), nothing happens (it behaves as though this weapon were not available, although it clearly is).
Is this a bug, or are those weapons a work in progress, or am I missing something obvious?
