Oh! Thanks for playing my game! That was actually my "first playable game" that i designed and programmed by myself. So i'm really glad that you enjoyed it! I really wanted to fix some Design issues (like the trash can that nobody sees at the end of the train, and yes, that's why you didn't know how to get rid of the food), but sadly i lost the original project file :(
Anyway, maybe someday i will return to it and start from scratch.
If you want to see my newest project (i'm working as design counseler and marketing guy) just search for "Wild Glory" on steam, it's really awesome.
