Well whether you're going to make a bigger proper game or not is your choice.
I wouldn't call myself invested per se... It's just interesting to see someone that is consistent in participating in the WGJ that uses the same characters every time as if it were going to take off one day. I just feel like being helpful to someone who is also a beginning game developer with passion.
I did check your previous game by the way; just that I didn't know what to comment about XD
Anyway keep up the good work.
