I was really impressed by this! The sprites and CGs look great, but I was really impressed by the monsters and how they were animated. It was very startling to see at first, and it was really cool looking. The story was also really good; I did Mimi's route first, and I felt it was so touching seeing the protagonist slowly reconnect with her. Despite how tense the trials got (especially that last one!), there was such a tender feeling between them.
In short, I loved it, and your team did an amazing job putting this all together! You managed to make something both scary and intense while also leaving enough space for heartwarming romance.
