Great game. I'd say it's worth the 5 bucks. I really like the art and animation.
It'd be nice if there was something more to keep you playing though. Like, after you die you just restart from square one. It'd be cool to be able to keep some of the money or something to spice up each playthrough. Additionally, the reward of getting new clothes is nice but nothing that keeps me coming back. It'd be neat if the experiments also unlocked a new animation or something.
At lastly, make the clothes have less durability >:)
