I love these kinds of brain test games! This was executed super well and from the audio to the visuals.
My only gripe is the scream from the whimsical shapes can be a bit jarring and, although silly, was a bit much after I realized they do it every time, and I had to lower the volume of the game as a whole which was a shame with how nice the audio was overall.
Ultimately though this is super incredible, well polished, and a great experience! Amazing work!
