Good binary number drill, but unstable

This is a pretty good binary number drill game, and it even has a bit of the "Flappy Birds" magic formula: quick ➕ hard => addictive ➕ fun. Unfortunately, as soon as I got to the 5-bit mode it started to crash sporadically on correct swipes. It doesn't have bright colors or splashy graphics, but after a bit more debugging and polishing, for an educational game, it'll be a winner.

Didn't expect to love this game as much as I do but it's really a lot of fun. The leaderboards make me feel competitive and make me wanna keep trying to improve my score. The one issue is that it crashes on the 5 bit version sometimes. Otherwise, a really solid app! Kudos to the developers

Clever game

I thought this game would be a little fun for a while...but I keep coming back to it. It's challenging but simple enough to learn in a minute. The animations and art style are really nice.
