Simple and straightforward gameplay. Once I got cozy with the controls the game felt like it was a matter of endurance. I could simply put the next number in place right as it was needed, so the "challenge" of the game sort of dissolves once you overcome the controls. One tactile change I'd appreciate is the "grab" animation -- it felt slow and would only pick things up on the way back which I found awkward. Love the game for what it is though :)
If you were looking for ideas on how to expand the base mechanics, here's some ideas:
- Don't always shoot the numbers out of the clock near where they're needed. It makes it too "easy" to just keep going in order and filling the clock "just in time".
- Make the fallen numbers be moving targets / roaming on their own. Different numbers could have different motion patterns. "Oh man not a 7, I hate trying to catch 7s".
- Powerups to: rewind clock, skip a number, move faster, convert current grabbed numbers to different value.
