As to the game itself, yeah tons of room for improvement. I also pivoted a lot during development. This was originally meant to be like "PG Fear and Hunger meets Star Trek." In fact, I bought Soldier Pack 3 during this period because I saw the scythe guy and was like "There's my ripoff Crow Mauier!" The noise sound effect was gonna be more prominent as well.
The battles, could definitely use work but I was trying to get away from them being "spam attack." The philosophy I was going for was "quick and lethal in one direction or the other."
