thanks for checking it out and the feedback.
if you haven't played it as many times as me, it can get hectic if you try to do more than choose where the animals drop from (which occurs every 2 seconds; 2x10 animals = 20 seconds). i get lost myself if i try to choose the drop points, work the gates and place dogs too often so i recommend just choosing where the animals drop for a while until you get used to the pace, if you choose to continue playing.
unfortunately, if i offer arrow-keys, i'd have to re-work some stuff and i'm winding down development on this but i'll consider it if i re-visit the project. but, i have addressed the Music as an option (see next post).
odd about the bug. i know that if you choose Full Screen from the bottom before the media loads, it will error, but i haven't seen/heard of errors otherwise?
otherwise, i totally understand "not for me". i feel that quite often with faster-paced games myself.
thanks again, and thanks for playing!
