What software did you use to write this game? I've seen the same UI on other games, is it some form of template? (asking for reasons of wanting to acquire said template if it exists)
it's a game engine called renpy! It is quite easy to use for very simple things like dialogue, scenes, and stuff, but mind if you do start to make games on it, minigame is a but more complicated. If you do want to use it to make a game, good luck! ^-^ ( I saw your bio in your profile x3)
