Hey hey! Sorry my reply is so slow, I've been ill since before Christmas, and only just starting to feel well enough to get back on my PC >.<
Thanks so much for playing the game :3 I'm glad you had fun with it :D Yup, wanting to add more yandere guys to the world is pretty much the reason I got into making vns in the first place, hehe x3 I was just gonna make 1 game, but I kinda got addicted along the way xD
Sadly, I am not the artist :( I can't draw to save my life, so any of the art you see in my projects is either the work of awesome artists that I've teamed up with, or art assets that I own (and have usually edited myself :3)
For this game, the sprite art came from asset packs by an artist called TOP. They sell highly customisable sets of characters, which is awesome! Basically, you buy a sprite body from them, and then it comes with a LOT of options. Like you can even create unique hairstyles because they provide separate strands of hair for you to combine! You can also edit colours, add details, and choose from a decent selection of clothing :3
I also used sprite assets from the same artist to create almost all of the sprites in my very first game (Solipsism Reigns) :D This is where they sell all their stuff if you want to check it out. (Just be warned that the site has some 18+ images on it too, haha.)
And the background art was by an artist called minikle, whose assets are very widely used by indie devs making vns since they are some of the most affordable, great-looking, and a fantastic selection of different locations :3
