wish it was longer =O
fun stuff, nicely put together. the graphics fit together well (esp for a shooter), and the overall feel of the weapons and movement was very natural. too bad people always release these 30 second demos all the time. few personal opinions on a couple things if you really get back into it -
*lower quality for fps part (or have an auto-quality mode)
*fps parts TEND to be more fun when you can take guys out in 1 or 2 hits, but guys appear in rapid succession and fire quickly
*have variation in color for shoot 'em up part
other than that it seems you have a good start for a game. everyone's gonna ask you to finish it - so ill just have to jump on that bandwagon. good luck.
