It a definitely an interesting game though it is hard to figure out what is going on. You have buttons set up for UI but no way to tell what the buttons do until you randomly click and experiment with them. UI may be a small part but it is very important for the player to know what part of your game does what. The overall concept of the game is a very cool idea but without knowing what's happening i cant really give an overall opinion or rating so for now id give it 2/10 simply because i don't know what's happening. Feel free to give my game a try id really appreciate it and feel free to give your honest opinion even a harsh one. https://marquae44.itch.io/zombliens
Yes I have. However visuals are still an important part of the game and for players who have never played your game before having to move away from the game to reread instructions that are listed elsewhere is a take away. You want your players to be constantly engaged and never look away from your game. I could easily rate the game higher but with me having to move away from the game to get some understanding its a negative. You also have to realize some people will not take the time to read the instruction which is why a very clear UI is important. UI should always be worked on in atleast some regard to give the player direction.
