This game was pretty innovative and I loved the art style!
The idea of actually diving deep into the human mind is an idea I kinda wish I'd thought of. But you definitely did the idea a good amount of justice!
A few things I'd like to note though. First, the game feels a little empty without sound effects. The neuron thing probably took a lot of time, so I get that you might not have had time for audio, but it really does make all the difference in how a game feels.
Second, sometimes the same word appears multiple times, which can be a bit annoying when you're trying to go one path, but the duplicate sends you down another.
Third, the typing seems a bit buggy as well. Sometimes it just doesn't type the word, and depending on your Caps Lock setting it might start one word, then jump to the next, but not actually finish until you realize you had caps lock on.
Fourth, the difficulty setting was a bit confusing. Why is it that when I drag it all the way to the left, I get no time, but all the way to the right I get all the time. Shouldn't it be reversed?
And lastly, I wish pressing space showed the entire dialogue and THEN skipped it, rather than just instantly skipping it. This caused me to miss out on the last bit of dialogue.
I know I complained a lot, so I'll end this review on a positive note: the game was pretty fun and I feel like has some legs as an actual Steam game!
