Quite easy, it's a shame no more stages really pushed it. On the below stage I thought at one point to go out the top of the top right one then drop down to the bottom right w/o charging; turned out much simpler than all that (though I still liked this puzzle for sure).
It would have been nice to see some more out the box thinking like that. Since you're so conditioned to operate inside this tile mode, when I did have to use the platforming nature of the game it really lead to an "AH" moment that's hard to pull off in puzzle games.
Overall though pretty cool. Was the style inspired by Stuffed Wombat at all?
