Shredsauce still has a long way to go, we all know that but Malcolm is doing this on his own. It will take alot of time to make new grabs, maps, etc. There are several options:
1) We pay for the game so he can hire a 2nd guy.
2) Idk how this rlly works but he can release the code so other people can build maps, grabs, etc.
3) He just keeps doing it on his own because he likes doing it and he wants to make the game himself.
