hey, checked out your game, rated it and am hoping you will come rate mine.
thought it was quite cool, only got to wave 5, its pretty hard defending both points at the same time, i guess thats the chalenge. but im not sure how it fits the theme.
art was beautiful, love your low-polly aesthetic. on of the best looking games on this list tbh amazed that you completed it in a week. though it would be nice to have a bit more in game feedback, such as recoil, and perhaps audio for things other than shooting. like when new items apear. or a buzzing sound for the flying creatures.
audacity's a free program that i used to do most of the sound efects for my game. the wind background noise was generated and edited from nothing using that. have a play around and get to know it a bit.
its that sort of visual and audio feedback is what i feel will take this to the next level.
cool game
