I like the unique setting and overall tone of the game (reminds me a bit of Super Mario 64 or the Ratchet and Clank series). Based on the tweet I know what I'm expecting when I go to look closer.
For areas for improvement I'm not really getting the Puzzler vibe from the screenshots. Maybe a video to highlight this selling point? I'd also like to see a similarly cute player character to match the backgrounds. The current one looks like a different IP entirely.
Keep up the great work and thank you for sharing!
