Hi!
I have 2 suggestions/concerns about the current event (and probably future events using the same mechanics).
1. There's no cap for how many times we can regain the creature's energy by catching snowflakes. At least I didn't meet this cap yet if it's there. So basically this means no balance and grind-happy event with a drastic difference of earned medals between those who can spend the whole day playing and those who can't. I'd suggest adding a cap around 1-3 times daily per pet for such energy regeneration methods. At the same time this will allow the devs to plan the event beforehand and give players certain purposes instead of having to adjust them depending on the number of grinders.
2. Touch device support. Some players can't use energy rergeneration game because there are no controls for touch devices. Adding left and right buttons to the game interface would solve the problem. Touch devices are quite popular right now so it can be an issue for a large number of players.
Thank you for reading!
