Really great game concept. Also the puzzly aspect is awesome. You have to think to get all coins. The switch up/down player mechanics is genius. I like asthetics, reminding me of old nokia phone games. Would be nice if the exits were marked/highlighted somehow.
Congrats on that great entry.
Happy new year.
PS: Sorry for mentioning not having sounds, my pc had a problem and I have currently no sound at all. Not your fault.
