Loved playing through this. The levels have a good progression with interesting mechanics gradually introduced. The puzzles are carefully crafted and fun, and need a decent amount of logical thinking but without being tedious or overcomplicated. The 'twist' to reaching later levels was such fun. The sounds are great too.

Over 2 MB uncompressed?  How will I fit this on my floppy!

Very fun game with a larger and deeper set of mechanics than I expected.  The care put into the puzzle building was very evident!
