Yesterday I've finished the game on a PC, and then finished it again on a phone right after. So yeah, I enjoyed it a lot!:D
The puzzles are complex enough to provide a satisfaction of a challenge, but the great thing is that the levels give flexibility to venture in more than just one precisely exact, step-perfect way from start to finish. All the new puzzle mechanics are well introduced and mixed throughout the levels to always keep you engaged and interested to see what's coming next.
The graphics design is a mix of 8bit color pallet and 16bit fidelity, with cuteness all around (murder kitties! <3) - original and very pleasant. The music is very nice as well, albeit it would be even nicer to have more of it;)
I definitely recommend it to... well, everyone!:D
Just three minor remarks regarding the newly released PC version:
The control scheme on Android is perfect and it feels way more natural than the one on PC. On PC I've played partially using keyboard + mouse (felt rather cumbersome) and partially with mouse alone (it feels less precise and the index finger tenses up from keeping LMB constantly depressed). I'm not sure how/if it could be improved for non-touch screens, but perhaps you could have a go at it and find a way to tweak it somehow.
Not sure if this is my issue alone, but there was no music playing in the PC version.
It would be nice to add a proper full screen/borderless window mode without the window handle bar at the top. Also when you maximize the game window in 16:9 AR the level title is not visible at the bottom.
