1. I believe this level is intentionally designed to be frustrating and rigged to make users pay to unlock the other exercises.Really entertaining and sometimes frustrating game it's a good challenge, and the ads aren't long or too annoying, and for $3 you can remove all the ads which is very nice :) no microtransactions or annoying notifications they said there might be a couple, but I haven't had any in the 2 days I've been playing.
2. You have to pass each challenge to unlock the next if you are a free user, and near the beginning is a "read the word, pick the color" challenge that is very difficult to pass in the time limit if you cannot properly see shades.
3. There really isn't anything that i can change by saying this but if you are color blind, i would skip those levels because you are going to have a hard and frustrating time.
4. TLDR: it's insanely good and I would 100% recommend spending the one time purchase amount to permanently unlock everything.
5. I had issues before where objects that were originally black in the light theme (such as the countdown) remain so in the dark theme, making it difficult or impossible to make out what I'm supposed to see.
6. The only thing I would change is that I wish the app kept track of your high score so you could see your progress and improvement 9/10 would recomendFun way to challenge the mind.
7. I would like to see my average score versus other users average scores, to compare myself and see which areas I need to improve on and which areas I'm better at than other people.
8. As a color blind person, it is nearly impossible to reach the passing time.
9. However, changing to light mode and back to dark fixed it, and I haven't been able to replicate it.This app works very well for what it says it's for.
10. It does not have to be a leaderboard, but a simple pop-up at the end of each round that says "You: 0.455 - User Average: 0.355". Make it an option in the settings, so people who don't want to see it can turn it off.Fun app.
11. This wouldn't be so bad, but you can't progress without clearing the level in average or less time without paying, which I can't really do.
