Cool game! I have a whole lot to say about this game, so bare with me.

So, let's talk about Run A B. IT'S AMAZING! If you watch my reaction, I got quite frustrated at level 2. Outside of that, this was a perfect game. The character design, the music, it's even open source, I'm flabbergasted! How you did this in a single weekend in bonkers. You should be very proud of this entry.
Let's talk about level 2. It was too hard for me. The dash + jump + dash + get up to the next ledge combo was intense. I would have liked for that level to be just a little more forgiving. Namely, it sucks when I finally get the jump and end up back at the start, hahaha. After completing the entire game, I was curious if level 2 would feel easier now that I was used to the controls, and it was still just as difficult for me.
Anyway, I love all the little details in this game. The settings menu incorporate the theme. There's apparently a chicken somewhere. It's fun to see the names of the levels after completing it. That's such a nice touch. This game is very inspiring to me. I really, truly enjoyed it, and I'm so glad I was able to beat it.
