Some parts were enjoyable.
how I played this
==================
Read instructions, played game, dying a few times but enjoying it, got to a level (2 from end, I think), just full of spinny blocks. Couldn't be arsed doing that, so cheated (I have a tablet), then played last level and last boss level normally.
some selected aspects (rated from ----- to +++++)
(note: I'm not rating everything or trying to break the flash up into constituent parts. Just indicating how much each thing I mention adds to/detracts from my enjoyment of this.)
===============================
+++: A bit of variation, brought upon by lava, switches, different patterns...
+++: I specially liked the idea in the level where the blue switch turns a block 360 degrees.
---: Not as much variation as there could be - in the last two levels, I felt it was a retread of previous ideas, with nothing changed - just the same thing lengthened.
-: It would've been nice to have some messages when you lose.
++: I like the way one level segues into the next.
overall
=========
A decent mousegame with some fun levels, but by the end it seems to have run out of ideas.
