Thanks for the feedback.
Regarding the gameplay I didn't go deep in explanation because creating the strategy is also part of the game.
Still it can be confusing because of the UI , I didn't get much time to work on this game as I joined late.
Also if anyone wants hint for strategy it's basically try to using tester tiles effectively to find the corrupted files faster than AI and send it to them, one thing to note is tester tiles can process files at same time means we can ask a tester file to test all the files at same time and it will be corrupted in 5sec as at least one of the file was corrupted.
Anything more than this will be you need to figure out :)
