im new to the forums, but i have downloaded and finished your demo
i must say i salute you. Great work for two team studio!
Solving the case was fun, exposition of characters through the demo was interresting too and good timing of demo ending hooked me for the full game.
I can imagine, that budget is small, but if you can, think about voicing the characters. Thats by my opinion only barrier between yours and fully aaa professional title. I wish you and your friend great sales!
