I think the artistic direction and throwing mechanic are really creative! The one problem I do have to mention is that the enemies are often hard to see against the background and tall grass - at least in the first level, I haven't gotten to the next ones yet. I'd also recommend the option to use Z or X instead of the left mouse button to throw an enemy, for those who prefer to use the arrow keys to move.
Edit: Ooh! I'll stay tuned to see how it evolves!
