I think the game is good in terms of gameplay. I like what developer came up with with the combat system, I hope it will expand and the game will develop in all possible ways. I wish success to the game and to you, the developer. And I would also like to mention one detail, when the boss is defeated, the waves, as I understand it, become endless. It's not very good because I personally got to wave 137 and my computer couldn't handle the game anymore. Maybe you will add some end after a certain wave and, as necessary, move it away?
