My only suggestion is do not take all the criticisms to heart its almost a great game, you essentially asked for negative feedback.
This was good. Part of the puzzling is how to use the platforms etc I played using a keyboard and had no issues with the platforming bits.
My only frustration is that it should be one puzzle one room or checkpoint, having to reset and re-do puzzles I already knew the answer to because I got stuck in a trap 3 puzzles over was no good.
My first run through took about 15min.
