Wow! Thanks so much for the in depth feedback, and thanks for the compliment!
As you have noticed, gameplay wise, the game is still a bit lacking. I was working on adding more weapons, such as nailguns, propane tanks (flame throwers) and a rotor so you can make kinetic weapons. But I had to scrap that because I ran out of time :(
I am going to pick up development with a friend, looking forward to what it might become.
