I have to say that I haven't bought the template yet, I'm thinking about it. Because I'm not sure that the template allows you to generate different enemies based on the type of wave. However, I'm also willing to pay you separately, if you can implement mechanics that are now sought after by everyone. Multiplayer Co-Op, attack mechanics in the style of Vampire Survivor / Brotato. In short: you simply have to move the player and power him up. Of course with various weapons and different characters. I think that a boss in a roguelike game is a must, as is the random generation of enemies and the environment. If you want and are able to create a version with these mechanics, I can pay you extra. I remain available for further clarifications. regards.
PS
Or if you make a new template it's even better.
