## What is renal summer?

You are a dog's kidney.
Your dog is in kidney failure and doesn't have much time left to live.
By assisting with kidney function, you can extend your dog's life a little longer and postpone the end of your dog's and old man's lives.

---You as a Kidney---
You recognize the blood as four colored blocks.
The blocks can be broken with a few taps and have the effect of "getting rid of toxins" and "gaining kidney experience".
Blocks are combined with other blocks of the same color, so the more blocks you put together, the more efficient you are.
The amount of toxins in the blocks, the amount of kidney experience and the difficulty of breaking blocks increases as time progresses in reality.

---Blood pressure---
Blood pressure is the force needed to break a block. The higher your blood pressure, the fewer times you can break a block.
You can use the "Kidney Experience" gained by breaking the block to increase your blood pressure.

---Blood pressure boost---
You can boost your blood pressure by breaking the green block to see the ad.
While boosting, you can break the block by just tracing it.

---The dog times---
Sometimes you can read clippings from your grandfather's newspaper, "the dog times", instead of seeing ads.

---Dog and old man's life---
The life of a dog and a old man who wakes up at 5am and sleeps at 10pm is tied to the clock on the device.
Watch their lives at any time of day.

### 2/5 — I don’t know how to start the game

*2021-02-17, version 1.0.5*

All I see is a dog running back and forth on the screen while a song plays in the back.  The song stopped after about 3 minutes and I thought “Ok, good. The game should start now”.  But no, the dog just keeps running back and forth and I have absolutely no control to stop it or skip or do anything.  I watched the dog run for about 5 minutes and then I lost interest, and I’m sure that other people will lose interest as well.  Maybe just a long intro? I don’t know.  But most people aren’t going to be patient enough to see it through.

### 1/5 — boring

*2021-02-09*

what is the point? you cannot expect me to sit here and keep a dogs kidneys clear. i think the real issue is with the old man. he needs to get his butt up and hike out of the woods he lives in and take that dog to the vet. i think relying on random unqualified app users to keep his dog healthy is very irresponsible!

### 5/5 — All pet owners should play this!

*2020-10-30*

It was truly a beautiful and enjoyable game. I had to say goodbye to my beloved dog of over 10 years this year due to illness and seeing the old man enjoy his quiet, simple life with his dog by his side reminded me of all the good times I had with my dog! It really touched my heart. The “Dog Times” articles emphasized the old man loved his dog and wanted to do everything he could for him (massages for renal health, special food, the special drone deliveries), which was true for me as well. Thank you so much to everyone involved in the development of this game!
誠にありがとうございます。

### 5/5 — This really pulled my heartstrings

*2020-09-11, version 1.0.5*

What a gorgeous little game. I’ve always admired pixel art and animation, and Renal Summer does this beautifully. Coupled with a gorgeous soundtrack and ambiance, I found myself wanting to know and see what was going on. Over the course of 7 days you get to know the antics of your old man and dog in their daily lives - from the farming, to playing fetch or them just hanging out together. 
The game gets progressively harder as you go along and see your kidneys fail and the blocks becoming corrupted. You have to visit more and more often to keep your dog from passing away, as well as upgrade your blood pressure to make the blocks easier to break. 
It made me think of my own dog and how much I love her, and the fact I won’t have her forever... so I need to make the most of what I have. 
Thanks for making this game, I loved it.

### 5/5 — Worst tamagotchi ever 🤣

*2020-08-30, version 1.0.5*

Seriously tho this game is brilliant. It’s so sad and dark the fact that you know it’s going to end and all your doing is prolonging the inevitable. I’m on day six at the min and it’s getting so demanding to keep alive but at the same time I don’t want my dog to die. 
I’m tapping away saying live damn you live but each day it gets harder and harder to keep him alive. 
It’s like nothing I’ve played before. 
Kudos to the dev for coming up with a original idea 👏🏻

### 2/5 — i don’t understand

*2020-08-29, version 1.0.5*

how and what do i do to play this game

### 5/5 — Crazy or what?

*2020-08-29, version 1.0.5*

What a mad game😎🤩🌮 was the time to get this game to be fun to be with your friends or you just want them and they are all you can do you know if you’re not sure you know how much they have to do it and they don’t have a job and they are just like the person that they are.

### 1/5 — It’ll make you wish you were the dying dog

*2020-08-28, version 1.0.5*

Hit the screen multiple times for no discernible reason. Until your life ends. Or like me, until you just stop.

### 4/5 — awesome <3

*2020-08-21, version 1.0.4*

super aesthetic and calming

### 5/5 — I am a good kidney.

*2020-08-08*

Beautiful game, thank you.
