was boring at first, but got pretty fun when the difficulty shot up ( and it shot up in a hurry btw) for future games i would recommend 1) make your own soundfx instead of finding them online, its actually quite easy to make laser sounds. 2) smoother difficulty curb, tho i liked it better when it was difficult, it really went from boring to insane way too fast. (3 spacebar would have worked infinitely better for a fire button, so my right hand wasn't trying to tap one button while holding another. but honestly not bad by any means throw in a decent soundtrack and you'll be set.
Love it! Great tribute to space invaders, like the addition of powerups and pressing down to heal! Realy starts to speed up after the first few rounds.
A very fun game!
The only thing that concerned me is the aliens REALLY start bombing at wave 3 and POW!!
Very difficult from that point.
Overall a fun game and an excellent tribute to an arcade classic.
