I love you chrome dinosaur
This concept, for how simple it is, is an EXCEPTIONALLY cool puzzler idea (like, how has nobody done this before?), I think this just needs more levels. The experience here is unfortunately way too short to get any real meat out of it, but you have a clear understanding of decent puzzle design and I hope you build on this a ton - you wouldn't need to flood the puzzles gimmicks either, I can absolutely see the concept expanding out into tons of cool puzzle solutions with just the one ghost. If I were to suggest gimmicks for a full title, perhaps some simple block pushing puzzles? With some touched up visuals and sound design, along with a proper suite of levels, I can absolutely see this being a full release. Please consider expanding on this.
