Dear NYU developers

I have severe ADHD with a late diagnosis at 23 y/o. So far I’m finding this app legitimately challenging but just enough so it doesn’t make me wanna give up, it genuinely feels like a brain exercise, especially when I reached the second page of levels. I’ve become super interested in Central Executive Training (CET) and I’ve been searching for ways to implement this training into my day-to-day, but most of what I find is research articles and just a couple of games such as this one.

Before I continue playing I was wondering if there was a way to reach out to the development/research team to give feedback, and to also ask questions, such as - is it better to play this game with or without my medication?

Thanks for taking the time to read my review, and thank you for all that you do :)

Thought drift sinks you

I am enjoying this game. It is a fun little diversion. What I find interesting about it is, if I focus I get easily get 100% of the targets. But as soon as my thoughts drift, I start missing almost all of them. If you want a high score, play when you can give this game total attention.

Level Select Screen is Glitched

Hello, I’m writing this to inform the developers that the level select screen is bugged. It does not allow me to choose levels I have already completed, with locks still over the icons despite three golden stars being under the lock. I accidentally reset to level 1, and would not like to restart all the way to where I was before.
