The game concept isn't new, but I like to play these types of games. The voice actor and the programmer have done an awesome job of combining all of these programs, and they're actually super responsive. I haven't encountered any bugs, except that on the main menu the bottom-left buttons don't work (the middle ones never, the quit button only on finishing the game). Maybe some more settings would be great, like subtitle customisation and/or language change.
I don't think that 15 minutes, nor an hour, is enough to playtest it fully. But thank you for this playtest opportunity and good luck with the development!
