I like the idea, taking "Breakout" and using it to represent the mechanics of the body (the heart passing blood between organs). This is interesting. I like the presentation.
I didn't enjoy playing the game too much though. The heart shape didn't feel conducive to the Breakout formula. (it kept hitting the side)
This may have been because I was using keyboard instead of mouse.
The audio loop also became too repetitive. Perhaps if audio was linked to each organ? So hitting them could switch audio layers on/off?

The presentation is very cute! I just wish the music weren't quite so repetitive.

Overall this is a very solid entry, so I just want to give two small pieces of criticism.

First: The foreground graphics feel, to me, like they aren't cohesive with the background graphics. I think this is because they are outlined and shaded while the background is flat.

Several of the pixel sizes also differ--that is, the point counter uses bigger pixels than most of the sprites. In my opinion using differing pixel sizes often makes graphics feel less like they fit together. This is of course largely down to personal aesthetic preferences; do whatever you like best.

Second: The music is probably too short--twelve seconds gets old within a couple minutes, in my opinion. That said, it is pretty good music.

I think that the game is overall very good. All of the gameplay seems very solid, and although I have my criticisms of the graphics and the sound, it still looks and sounds great. I like the little personalities that all of the organs are given; they are very cute. I also like the mechanic of generating and transporting resources between the organs.

This was fun. Cute graphics, nice music. Thanks for open-sourcing.

I like the artstyle with those faces on everything XD plus a clever use of the theme into a classic of gameplay, yet i like the new spin you put on it with the different organs just resting a bit before being hittable again to score instead of the permanently destroyed brick of the classic formula.

The game also feels very polished overall with the themed UI and color palette, no particular issues for me when playing this so can't really add more.

Good job to you guys ^^

A nice take on this classic genre :) 

I especially love the artstyle, simple yet so effective thanks to this limited color palette !

The shape of the heart makes it sometimes hard to precisely control the ball, but I had a blast playing the game :)

Cheers & congrats on the game !

This remember me something.. good job bro

The Menu UI is so satisfying to click and move around. The whole color pallet fits well and is consistent. Game-play was fun and addicting . Trying to get high score. I like how each organ has some effect. 

A fun, polished game with a satisfying Menu UI. Good work!

This was really fun. I like how you had to make combos with hitting the organs with the right items to score more points along with them going on cooldown so there was not constant-bouncing. It was just hard trying to control the heart with the mouse, especially when I don't know the heart's collider and bounding box.

Love the visuals and overall idea. Having the trails on the ball is such a nice little visual clue to where the ball is going.

Super cute! Really enjoyed playing, great art style! :D

Solid game! very original idea!  loved your game my best was 83 lol 

Very cute organs and colour palette!

Solid, polished game!

(If only the Liver was not so evil )

Congratulations! Good work! I liked the originality of the game
