Hey! Cool game, it's not the only one I've tried with the same concept of getting buffs after enemy waves, but I think it would be cooler if you had stacked effects instead of just 1 per round, at some point the controls randomly decided to invert and change, it felt intentional since even the WASD movement was inverted but I didn't knew why it happened and was very awkward to play. The music was very inmersive but the slow action of the game didn't made justice to it. Maybe making a bigger map and adding faster movement would make the game more addictive and satisfying to play. Keep polishing it, it is a promising project!
