I really liked playing this and it surprising run better than mineclone2 for me, and since i have a crap pc this is big news i only have two issues with it 1 of the issues i have with both this version but the other issue is specific to this version more than 2.
Issue 1- this is the issue i have with both mineclone2 and this one, is that it lack the minecraft inventory option of for example shift clicking to craft many items/blocks at once, stuff like being able to get multiple items of the same type in a chest at once also don't exist this make inventory management a bit more harder or annoying to do, and i kinda miss that inventory QOL shortcut that minecraft has.
Issue 2- now this is a issue specifically to this version, the mobs hitboxs is very weird sometimes i swear i should hit a mob and yet it don't, but i think the major issue related to mobs is that the spawning of enemy mobs like zombies and skeletons are barely spawning at night compared to mineclone2 and this really bother me, in fact i'm seeing a lot of passive animals and barely any of the offensive enemies.
Anyway i know this is a WIP and the devs will probably fix those issues, but if you gonna play the game have this in mind before trying it, well if you care about that type of stuff like me, some people mentioned bugs in the comments but at least so far besides the weird hitbox thing and weird spawning for enemies i didn't notice anything else major in terms of bugs well if you consider those bugs.
Edit:Forgot to mention the lightning on the mobs is really weird especially if you play with a high gamma, i have a high gamma and the blocks and everything else looks fine but when night arrives the mobs (including the player) end up looking super dark compared to the blocks even with the high gamma.
