A good and solid idea with some technical difficulties... I enjoyed it eventhough i am not a big fan of the genre...
Some notes:
The text on each character did not delete and every new text kept going on top of the previous one which made a mess by the end of the intro story...
The cows move way way too fast... I could hardly catch them with the mouse...
Add some more explanatory text ingame... I had to play it 3 times to figure out what i had to do..,\
Keep it up
