Thank you! Makes me happy if you liked it!
I have chosen text over image for a specific reason: It forces your brain to interpret either “color” or “symbol”, so keeps the concentration up and trains brain-flexibility. After like 30 completed games during testing i found out that i solve level 5 with most of the timers at 50+% left - so for me it is now waaay too slow. The training effect occurred quite fast - I must confess, I was very surprised, HOW fast. I had a brain-training in mind when doing this (I am a teacher, so I often think in that direction) but it really helped improving in switching interpretation context if you play it several times.
