Hey Mew! Thanks for playing! I'm glad you liked the whole concept I went for :D!
I do agree the gameplay is pretty monotonous but that's how I feel about that type of game in general (although my version probably was even more monotonous because it lacked good balancing lol!)
Yeah so the way the waves are spawned is that the code picks a random enemy from a predetermined array, turns our if you're not careful it will deplete all the strong enemies first so there is definitely quite a bit of fine tuning to be done there!
I did think of making a thingy that would show the stats but that was way out of my time limit, I started two days late and published this game on family trip soooo not the most productive environement lol!
I'm not sure I understand what the screenshot is for though..
