This game... is so pretty! The art is adorable haha. Everything from the title screen to the in-game characters and UI really fit together and hold a consistent sense of tone.
As for gameplay, I didn't know you could make rock, paper, scissors be funny and exciting, but here we are. Everything comes together really nicely - from the ridiculous premise of nuns fighting monsters, to the dialogue that naturally teaches the controls, and all the SFX that take place during combat.
I also love that you can speak with the nun. I spent some time just exhausting her dialogue, because I was still just absorbing how great the premise is, and she really helped to set the scene and immerse the play in the situation... and make me a bit needy for some tea.
I think the game did because pretty easy and even muscle memory once I realized that all I had to do was press the button to the "right" of whichever one the enemy had highlighted. It might feel more dynamic if the button colors were swapped above, which would force players to pay more attention.
If I could offer one major feedback, it would be to export a web version. Since this was made in Unity, it should be possible (with some bug testing). I think you'd get a lot more plays that way, and this game definitely should tried more.
Great work! This game had a lot of charm. I wish it was expanded somehow in the future - had more mechanics, more characters, more dialogue - in a way that kept true to its core yet still introduced more things. Maybe bosses or enemy types with unique mechanics... as ridiculous as that may sound. Regardless, I really enjoyed my time with this one.
