Really love the art and the gameplay concept!
The level-up system was cool in adding new monsters and candy for the player to grab. I like turn based card/board games, so this was right up my alley. I did have to learn the game through trial and error, as there were no instructions in the game. I initially thought it was a match-3 style game haha.
My only real critique game play wise is that it didn’t feel there was enough risk to the player. It might be nice to have a bomb style card, that if it doesn’t get solved in X amount of turns, it blows up damaging the player. Just any sort of effect to keep the player on their toes or to pay attention to the configuration of monster cards on the board.
In any case, I had a lot of fun, awesome job!
