Really good idea, I love it! With some extra polish this could really be a great game. One thing I might add, I think this game could benefit from being a bit faster paced. It would be so much fun if we had to fend off much faster enemies, and higher in numbers too. Of course we'd need to be stronger too. Both towers wise and maybe additional powers to the player besides clicking? Oh and also, an indicator for what needs reloading would be a nice QoL feature. Congrats on the submission!
