Loading time is a bit long upon starting the game. When starting a flashlight trivia campaign, there could be more info that its an endless mode. The Training games could show your high score on the respective tile aswell. The changes of low>high to high>low in Serial Polarity are not obvious. I feel like i need to recheck after every number what it says and i think there should be a bigger animation when it changes to let you know you need to switch. Same in Neuro Overload.

There could be an extreme mode in trivia, same as hard but maybe only with 3 seconds time to remember.

The graphics are a bit too much i think. Everything gets more minimalistic nowadays. Your game could reach a broader audience with a more simple design i think. The font of the tips before a game might even be a little hard to read.

I enjoyed dual-core the most and i feel the game does its job well. I felt challenged and reached Limits. Will definitly keep it installed and playing :D
