About 异常 | Exception

https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/621000/extras/desc_exception_en.png
Exception is a game about AI programming. During the game, the player assists the units to defeat their enemies in the virtual world. However, the player needs to control the units by programming instead of controlling them directly.
https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/621000/extras/anim_battle.gif

This is a challenging single-player game. In each level, the player needs to think about the strategy and program the units accordingly. The player needs to program different types of units to beat the level.

https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/621000/extras/desc_story_en.png
In a virtual world where everything operates steadily under an omnipotent system, you will play the role of an operator named 159, who oversees and maintains the system.
Nevertheless, there is no perfect system. You find an exception in the program one day. What is stranger is that the program made a request…
https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/621000/extras/anim_story.gif

You will discover the secret underneath this cyber world.

https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/621000/extras/desc_programming_en.png
“Exception” implemented a simple and unique graphical programming language for the game AI specifically.
https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/621000/extras/anim_code.gif

This programming language is very simple to use, and anyone can easily get started with a little patience.

https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/621000/extras/desc_battle_en.png
When you have finished the program for your units, they will fight automatically according to your instructions.
https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/621000/extras/battle_anim2.gif

We can no longer intervene in the units once the battle begins, you need to restart the level if you want to modify the program.
Of course, constantly debugging the program is inevitable, and victory is born from failures!

Not recommended Dec 26, 2023

You know what, I almost completed the game. Did 26 out of 30 levels or so. Few levels I've beaten with RNG on my side and it's just that RNG that doesn't allow me to give good recommendation for a programming game. With the same set of instructions, my unit sometimes gets the shot off correctly and after restart it just doesn't. And I just don't want to spend time working on second phase of mission if I have to dice-roll for passing the first phase.

For the price -this game is totally worth it. The biggest annoyance with this game is that it doesn't give you all of the tools at the beginning and let you solve problems in an increasingly more complex way - instead it adds more tools as the level complexity increases which is very annoying.

Recommended Nov 16, 2025

A cool game to figure out bit by bit. And when you think it is over, there is a bit more to experience.

Not recommended Nov 10, 2023

Limited solutions for the puzzles.

Recommended Jun 5, 2022

very good game which requires your logical thinking skills and programming skills. Kinda addicted sometimes.

Not recommended Jun 22, 2021

As someone with programming experience the visual programming was slow and tedious, the problems werent interesting, the solutions not statisfying and the narrative didnt hook me.
