I started during the first lockdown here, first on Bedrock on my phone, then started Java on my laptop. 1.16 I think. Got hooked pretty quickly and it really helped with the stress of what was going on.
I started playing on bedrock and moved to Java. Think I prefer java but there are things that I miss on bedrock like being able to bonemeal flowers and seeing the colour of shorn sheep. Silly things but I still miss them. Mind you I remember Magma cubes being way trickier on bedrock (or maybe I was just new and rubbish). The first time I went into the nether on java i jumped straight out again - the noises completely freaked me out lol.
