This is one of my favorite tower-defense games! I have sunk waaaaay too much time into this on the Android version back in the day. I really enjoy tower-defense games but quickly tire of them most of the time as they lack any real depth. Mindustry felt much more complex and nuanced to me. The only thing that I might have wanted would have been a bit of story, but, honestly, the gameplay is strong on its own and I don't feel like I need it here.
