This game is definitely shaping up to be a winner. Being in its alpha stage, I can work with some of the missing elements (i.e. breeding animations, donation functionality, and monster housing art) but there are some issues I noticed.
First, breeding monsters is very cumbersome. I've found myself clicking constantly to find the two monsters I want to breed to increase particular stats. This gets particularly annoying when you have a full monster housing. I think a side-by-side breeding menu would be particularly helpful. Maybe even a filter for male monsters on one side and female on the other?
Second, when you harvest a monster, I found myself clicking numerous times to move to the next monster. I bet a "next button" would serve to quicken harvesting and lessen frustration.
These two were the big issues I had with this version of the game. There are some small issues that other reviewers have pointed out, such as the text being too difficult to follow. Some more refinement will make it add to the story rather than distract.
Bottom line, you've got a great game that needs some fine-tuning. I am definitely looking forward to the finished product.
