Thank you for the feedback! You're absolutely right - I should have been clearer about this being an early demo.
I've updated the itch.io page to clearly label it as "Early Demo" with ~10-15 minutes of content. The game is still in active development, and I'm working on expanding the content with more elements, prestige layers, and features.
Your feedback helps a lot! If you have any suggestions for what you'd like to see in future updates, I'd love to hear them.
