honestly incredible vibe. the controls for keyboard took a little while to get used to, but the fact that I had to learn them on the fly while enemies were attacking from all sides and the crazy music was playing actually made it fun to be under pressure! although my one issue is that I didn't have enough materials to make anything after the first wave—not too big of a problem, I just think it would be cool to afford a tower or something else right away so you can decide whether to spend it immediately or save up for something stronger (idk if the materials enemies drop are random, so if they are that explains it lol). overall great job!
