I loved this! So much fun with so little :D I think the flamethrower could be more powerfull, since I ended up using just the machine gun. I like that each wave has a different twist, they could be even combined the more u play. Sometimes the audio was really glitching a lot, but maybe because there was so much happening at once :D Really fun game! Oh and yeah as others mentioned, SFX needs to be improved, just add bunch of sfx to the guns, make it random, add music maybe, it really does help a lot!
