It seems like an interesting way to convert some of that galasilver into something more useful every day, so it's pretty cool.
My feedback for the dev would be: perhaps it could only be 5 galasilver to play, as you'll be wasting a week's worth of progress most of the time trying to get to that $0.20 of galacredit each time and it is very hard to consistently get 1st every time. It doesn't seem like an unreasonable ask, you will still be using at least 3-4 days worth of galasilver even if you get pretty good at the game.
For those that struggled at first like me:
- Starting right on the dot is very important, try to stroke your first key right exactly when the race starts.
- Use only one hand (your left or right or alternate) and alternate between fingers only on that one hand. Using both hands really really really messes up your pace, don't do it.
- You don't actually need to hit the keys that quickly to take 1st place, timing and rhythm are actually more important than speed (though perhaps with a little more speed in the rhythm you can actually consistently take 1st every single time? not sure yet)
