Thanks for playing, and thanks so much for such a thought-out, well-written review! I was afraid that the high difficulty and obtuse tutorials would be off-putting to most, so I'm glad you found enjoyment in it.
The "dense" feeling of the levels is a bit unintended; I tried to showcase all the main mechanics in this build, but didn't have time to make enough levels to pace them out. I will definitely be adding levels in future builds to ease the learning curve a bit, but rest assured that the levels I add will be just as satisfying to solve. Thanks again for your feedback!
