This game is actually not that hard if you sell animals. Every animal you sell you can make a tidy profit on. For instance the starting turtle creature costs 15 to make and sells for 70.
I wonder was it intended that you should only be able to train up to 3 creatures at a time? If so the game would have a better curve. Currently money is meaningless as long as you're willing to click.
Also Agree with the ui buginess, lots of random scrolling, difficulty in clicking, and well just lots of clicking for buying stuff. The equipment seems not fully utilized. I went through the game without even thinking about it or using it.
Not a bad game overall though.
