Interesting game! I found the mechanics a bit to difficult to keep up with the pace of enemies spawning. It seems like the tanks take 3 hits, I think ? but by the time I managed to get one, two more would spawn, and I would quickly be overwhelmed with mobs. A buffer zone which prevents enemies, such as the rockets, from spawning on the player would be nice too. The design overall was really cool though, and I liked the art of the entities. Nice work!
