Absolutely fantastic game. I've been playing for about 6 years now and I have yet to encounter any issues with saving my account or losing progress, probably because unlike the people giving 1 star reviews, I actually save and load my progress. Anyways, the game itself is outstandingly good. It's extremely fun to play especially getting into harder community made levels. There are quite a few bugs with gameplay, but they are all super minor and don't bother me whatsoever. Great game 5/5 stars.
