Lol, that wouldve been a legendary collab, we welcome the little flame guy in the Keep the flame woods anytime! I bet a campfire would feel a lot more spacious than a candle :]
I get the different canvas size messing up pixel size, had a similar problem a few jams back, but I think that it doesn't always look bad. I'd love to see The Last Ember with pixel perfect art, I believe that you can make it 10 times better!
