Your english is nice, don't worry.
"....UI (scoreboard or inventory) I don’t think this is the realm of originality, but if I’m wrong, I’ll change it."
I believe it would be for the best to differentiate the scoreboard, it is basically identical to Deadbolt and it truly comes of as unoriginal and a shameless copy.
"...I will contact Deadbolt developers, and if there is anything they are displeased with, I will change it differently"
That's a nice attitude! Keep it up!
