Fun and challenging
It was pretty frustrating to have a really hard level ten in The Rockies right after a fairly simple set of levels, but I'm glad the challenge was there. Perhaps the earlier levels could be more challenging?
The graphics are fairly simple, and not unpleasant, but I feel it could do with a little refining, especially the little characters.
I felt having a penalty for using the rock-throw aiming line was a little unfair, since the aiming is not exactly where you click the cursor. I failed numerous times guessing how far and high the rock would go.
Only other quibble is that the restart button (R) is right next to the action button (E). Accidentally restarted a puzzle that I was almost finished with, and it was pretty frustrating.
Liked this game, and the shortcomings are not a huge issue, although I highly recommend these be improved for any future games of this kind.
