it was a pretty good games, maybe have the enemies shoot back and some health replenishing options and being able to buy health upgrade. of course more weapons and enemies, but also make it so you can upgrade the main characters weapons rather than just the turret, overall id give it a 3.5/5. not bad for your first released game cant wait for the sequel..also in the meantime you should think of a better name instead of the generic "turret defense" title that so many other games have
