Looks fine to me, but I think having the ninja back in his original position have his sword out for awhile then having a slashing animation on the knight. It's your game, do whatever. :D
5. If you messed up anything during your own remake so it's almost unplayable, I suggest you delete the Miner Life folder and download it again.
Thanks for this questions too! I'm always on my feet to answer any honest questions. XD
Alright Aiden, to answer all you questions,
1. No, it is not a demo, just a small updating game soon to be big. :D
2. Saving will come out soon.
3. The problem is a secret until a later update. Lets just say it involves fighting. ;)
4. I do not have an end command anywhere, must have been something you accidentally added.
