Frankly, I like the game Lucky Block a lot. But I think it's not good enough. I'll just say the bugs in the game.
First of all: Cheat detected error in the game. I think this is important if it is not seen very often, because this is a glicht. By using this, people can introduce more bugs into the game, I think it should be fixed. I think you will experience this error when you use a flying block. My guess is that the system sometimes does not recognize blocks. Maybe if you add a better system to lucky blocks the problem is solved.
So sometimes you can get 10 of an item, sometimes only 1 item. This confuses the players. Maybe you can add a chance percentage system.
