Couldn't figure out how to link email so am writing this review in hopes I'll get the other features unlocked.
Random number generator is good, just wish you could customize more: change what intervals it's random i.e. by 0.5s or 0.001s; how many numbers are generated; whether numbers can repeat.
Random direction is fine too, but again should be setting where you can just change it to N E S W, or choose how many slices the pie has so you can do things like spin the bottle.
Other ideas:
Could add a custom one where we can input our own words i.e. people's names, restaurants, colors, etc. and let us choose how many of these items are randomly chosen. For example, I enter ten names, and RandomChoiceMaker randomly picks two, so these two can be the captains of a basketball game.
Also a random word/letter generator, which would be good for freestyle rap battles.
I would probably edit this review and rate higher if I saw how the other features worked.
