Nice to see another artist like I trying to make their first game :D
the concept seem fun especially if you could make puzzles like fireboy and watergirl. I have an idea for you though, seeing that your characters are a dog and a cat why don't you have a timer like in n and when I runs out the game ends on a screen of the dog trying to eat the cat.
I like what you're doing already but its just an idea (maybe a little too ambitious of an idea considering how much time is left). Cant wait to see what you end up with anyway if you finish in time :)
