You probably want people to play your game. So, try not to punish them too hard ;) restarting the game every time you lose is really annoying. And even if that's the title of the game, it's not a good game mechanic. At least not in this context. The first two mini games (dunno if there are more, because the game was too annoying) were simple but fun. I would thought about focusing at one of them, to make it even better and add more levels. Especially the first game with the calculator would've been so easy to expand simply adding more buttons and more difficult levels (maybe with more than two moves, even if it's off-theme then. You still have the goal to reach 2 at the end).
