Hey Ivory! Nice game you have here! I really like the concept of this game--making a monster with specific characteristics is a very relaxing and fun activity. I also really appreciate all the art you had to make for this! The art is very cozy and cute, and it comes together in a nice way.
I think one thing you could do to improve this game is actually increase the potion count. With a game like this, I really want to explore every possible combination and outcome I could make with my pet. However, with a very limited potion system, it becomes hard to do. If, for example, I had a blue monster but I wanted to check what it'd look like with red, then I'd have to use up 10% of my potions just to check and see whether I'd like it or not. Perhaps one thing you could do to still keep the urgent feel that I think you were going for is make the timer go a bit faster and make the potion count higher. This way, I can still have fun exploring the different options I have, but still know I have to make very quick decisions because I'm on a time limit. Just a food for thought!
Also, a restart button would be very handy!
Overall though, I thought this was a very cute game. Good job! :)
