Better SFX...
First off, great game! I enjoyed it rather throughly. My only complaint is the sound effects. It sounds like, and do correct me if I'm wrong, that all the effects were made by mouth, and not downloaded and located. Now certainly, that is rather novel, but the single thing that detracts from this game is the "pishew" noice made whenever one of the droids explodes.
Aside from that one small complaint, this game is amazing...simple, but very fun. Keep up the good work, and I hope to see a version with better SFX, and maybe a background or something snazzy to spruce things up.
