There is so many bugs, which hinder you from progressing. I tried hard and had to restart multiple times... until the point where i got to the last wave. I made it, but it bugged again and didnt finish. It took me like 4-5 hours, countless restarts. Cards are bugged and all. But its hyper fun! More content needed! And some bugfixes, then I would definitely want to play this for a long time! Its similar to stacklands, which was great, but lacks content
