Just been playing both this Alpha and the previous one (4.2). Generally it's an interesting concept, but I think the following need addressing.
The control system is all over the place! this is a big problem in playability. It's all very fiddly.
I would suggest the animation screens are closed just by clicking anywhere in them not having to find the X in the top corner.
It's fine to have a continuation arrow If there is another animation to follow, but to exit out it should just be a click anywhere else on the panel
The feeding/Harvest in each pen might be better with a screen similar to the breeding or buy screens, these are much easier to use.
at the very least, it could be an idea to have a next monster option so you don't have to exit back to the main pen to select another monster to feed/harvest.
The current mechanism makes feeding/harvesting lots of monsters quite hard work with lots of clicks.
Generally you are using all types of buttons and controls to do jobs like exiting a screen/panel. Try to keep to just one consistent type and keep them in the same location on the page. Switching from top-right to bottom-left is a real usability pain in the rear.
As the game progresses, you need to have some consideration for the player. He/She needs to be able to quickly manage all their monsters. Potentially they could have 30+ monsters on the books.
It might be worth having everything on one screen, incorporating breeding, feeding and harvesting. You only need to go to the pens just for the view/atmosphere.
Like I said, I quite like the concept you have and the animations for the various interactions are great.
I've thrown several ideas in here and not all of them work together, but you do need to make some consideration to playability before you progress any further, graphics can come later. With a nice to use interface in place you can then concentrate on the fun bits like drawing what happens when you harvest a kittengirl or a demon
finally , just a comment
I think I liked the graphic style in 4.2 over 4.3 ... sorry to your collaborators on that.
Maybe have the graphic style for the backgrounds similar to the animations style (if possible).
Keep up the good work.
