yeah, deferent enemy's is my current to do. im also going to add a randomly selected boss every 10 waves
controls are a trick because of the 2 player aspect. i might make it so if you select 1 player mode you get a traditional 8 direction base with a rotate to face the mouse aiming.
cross hairs is a good idea

"BTW there was a VERY cool MMF game that you controlled a group a soliders fighting off waves of bugs, but I can't remember the name..."
i think the game your thinking of is aliens infestation 2, that and tremors 3 were kinda the inspiration for this.

i submitted 1 of the crashes (the one that crashes when i tried to save the level made in the in-game editor). it was an Anonymous submission though. the other one happened way back in the day when construct switched to a newer version.
i might pick up the pieces and remake them after version 1.0 comes out.
