I like the concept, and I do like me a good beat 'em up.
But it feels a tad.. Flat? Like it exists and that's about all it does, sorry to say..
Although I will add, the candy working as both your HP and points is interesting, I like that.
If nothing else, I give plenty of credit to you for making a game in just a week, that's a big ask of anyone and you did it, well done.
