Played this after seeing some posts on Reddit that made me curious, as a current IT employee and having done 3 years of IT phone support this is bringing back memories of all that I had to deal with.
Love the concept, and the minigames really do add some much needed variety to the tickets. One suggestion, maybe add a counter to them to show what the minimum goal is? Sometimes I forgot what I needed to reach and succeeded just by luck.
Really suggest that you look up PirateSoftware on Twitch and YouTube and see if you can get him to try this out on stream, he's former IT and a Game Dev and could give some feedback as well!
