This game is really entertaining and well made. The idea of catching snowflakes is very simple and relaxing, but there's enough to the game that it's easy to get sucked into it. The different snowflakes and upgrades, plus the new power ups, really add an entertaining dimension.
The one glaring problem however seems to be a lack of stability for saving. I've been playing this game for around a couple months I believe with no issue, until today when I discovered all my progress was deleted. Reading through the comments, it doesn't seem uncommon.
Since games like this ride on being able to resume progress, despite how much I love it, I can't justify spending hours on a game just to have my progress randomly deleted. If this issue gets fixed, that will make this one of the best idle games I've ever played.
