I liked the design of this game. Feels like you are a secret agent, neutralizing threats on your system. I especially liked the techy description of each action, as well as the techy UI; especially UI. It's very well made.
The only thing I can note about design, though, is the music choice. I expected something 'stealth-y' music, not casual music from arcades.
The gameplay was fun, despite its simplicity. Who would have thought checkers could be that fun? But I have to admit, the first 4 levels were easy. I think you should add more secondary (or even mandatory) objectives, just like in the 5th level. For example, lose only 1 chip, or promote a king to the enemy, etc. You can even make a level where every enemy chip is a king. That would certainly be challenging!
In conclusion, a great game with amazing design and fun gameplay. Needs some work on music choice and more challenges.
