Yep, we know about that one. Thanks! Please use the Forum for bug reports in the future. Much better place for us to keep track of them and respond to them. Yay.
If your computer is running slowly, zoom out of the screen to decrease lag by pressing ctrl+minus. Zooming too far out causes some images to disappear, but toward the end it doesn't really matter.
A few complaints:
1. The combo thing or whatever(I can't be sure) is overlapping the score(explaining why I can't tell)
2. The enlarge power fade very quickly, and it is difficult to know when you should compensate for it
3. There seems to be no change in difficulty throughout the game
I give it a 3/5 for being a simple, but enjoyable game
evolve monster surely get more cap max stats.
