Hey there! Thank you so much for checking the demo out :D and thank you for the feedback, it really really does mean a lot! I’m really glad the atmosphere and graphics really landed well for you - I’m happy to say the glitchy tile bug has since been fixed for the full version and will make its way into a demo update soon, that’s very interesting with the game slowing down after 4000 points though, I’ll be looking into that very quickly, I imagine this will be related to the third issue you listed as well so definitely one I’ll want to get fixed
Great job on such a high score too!
