Glad you liked it!
We'd love to add more content if/when we expand the game in the future.
If you send me your hardware specs (OS/CPU/GPU), I can look into those performance issues!
I have ideas for the game. Maybe then in the future you could add a "survival mode" where the monster will get stronger, faster over time, and there is a timer that measures the time to compete against friends.
Maybe you can add more items too. When you hear a specific sound from the monster, the flashlight will not work. You will need the new item to counter that attack. What do you think about it?
