This is a system I have made for kicking down doors! When a player is near a door, they can press F to kick the door down. Here is a video that explains it.
This system is for sale! If you would like to purchase the system, the video explains how to contact me, and there is more information in the description of the video.
Can I ask how much you would sell this for? So I can well criticise.
Not entirely sure, do you have any idea how much would be a fair price? (in robux) (i have no idea how much to sell it for 
)
I’d say 50 robux. Or just free as in my opinion its not really fit to be sold or bought. I would say that you need to work more on this. Things I don’t like include the fact that the door breaks. I have never seen a door break from a simple kick. Unless your omni-man. And a few more polishing touches like how the leg kicks? And the SFX etc.
It’s not intended to be realistic, also 50 robux is just not worth selling it, thanks for the feedback!
Exactly, so first improve on your design then talk about monetization.
There’s nothing wrong with the design?
I’d set a starting price at 250 Robux, since it doesn’t seem to be that complex from the outside, but it’s still a neat system.
I would imagine a more polished and improved version to be sold at 400 robux or above.
In the picture they press F though 
This is literally ~$0.12 it’s obviously a small and simple system but at least give a realistic figure
I’d say around 400-500 robux would be good for it
Oops my bad lol I typed G instead of F
Thats my opinion right there on paying 50 robux. I wont be giving a “realistic” figure as the system is not really too polished.
