Muvslide is a non-game project developed by Forest Indie Games, at that time, a one-man studio.

The project born in early 2015, and is being published in 2018. The reason behind this is that I don't just developed the tool, I conducted a cientific research to validate my work and its applicability in the market (i.e. whether its precision is good enough for using it in comercial products).
