Gorgeous pixel art, special mention to the animated megaphone.
I was a bit confused with the enemies, I wasnt sure if I was supposed to spray them or ignore them. There was a lot of info thrown at me from the start and I didnt kept all that info, maybe slow down the progression and only bring up enemies on the second wave so you can focus the megaphone text to that information. Also it was pretty underwhelming to not have anything to buy for several waves in the in-between wave shop. Also currency wasnt displayed during the shop so It would only tell me I cant buy anything without me knowing how much I have. Also since I was clicking everywhere while playing, the first time I could actually buy something I clicked something without wanting to since the shop open really quickly while I was playing and I just clicked something, not sure what.
Really nice art and good job for the game.
