Good Work
Graphics
I loved the graphics, not just the character graphics (which were very cool) but I really liked the tiles, how every level seemed to have more and more new graphics to it. Thats what lots of puzzle/platformer games need, they need new graphics every level (as minor as some could be) the graphics went along with the code very well. Liked how when you had the animal talking after one died it would switch to the next.
I really did like the art, I really liked the size to them for some odd reason.
Code:
Code played very cleanly, I liked how the animals exploded a lot, though maybe more of a blood effect then bricks of animal carcass. Didn't really appeal to me to be honest. But I liked how the game played in general. Liked the boulder puzzles, those were cool. Didn't quite like having to jump on small bricks, I have always hated that in games, just seems like a waste of my time to jump on small bricks instead of having puzzles to figure out. I liked the boulder one where you leaned the panel and the boulder on the string rolled moving the panel then dropping, which to be honest I should have seen coming up but I didn't... so I died.
Concept:
I like the concept of cute little animals better than cult members, and I think the forest levels were very nice (had lovely tiles) but I really didn't like the way they spoke "the bright ouchy water" "The spikes make me feel ouchy" It seemed way too (I dont want to be an asshole by bringing this up but) Happy tree friends in the way that you tryed to make them cute so killing them would be fun.
If it was straight forward with animals trying to get to the valley and told you it instead of making them really cute and making the game feel so much more like Juvenile in the delivery of the animals.
Thats my opinion, but it really was a lovely game.
