Looks snazzy but this addon feels ridiculously overpriced. Look at other addons on the GMs, there are plenty that outdo this on content, models, code etc but are still lower price. Look at pretty much anything by Zero (Like his newest release). WAY more content in it, and it's less than the price of this addon at it's base price (This is still more expensive and apparently it's 33% off.) Zero's most recent addon has a butt-ton of custom models and such, custom animations, UI etc etc and only costs $8. Are you really trying to say that you think this addon took more effort/time/coding than that one? Doubt. You've nearly set this at double the price, and to be fair this screams "Weekend code-job"

Also not to be "that guy" but this addon basically already exists for free since like 2015; https://steamcommunity.com/sharedfiles/filedetails/?id=433932042 (Say what you will about it being "ugly", the point still stands.) You've effectively taken a free addon, cleaned it up and added a few teeny tiny models in and set it to be one of the most expensive addons released on GMS in the past few weeks, only being beaten out by literal auctionhouse systems and character creation things. A lockpick. $15. Wat.

I wont lie though, this version has included more features (Visible 3d model and such) but for what this is, I cannot understand the reasoning on the price.  It's... Not that dramatic of an update in the grand scheme of things. A bit of a cleanup on the visual ui and a few little circle models slapped onto doors. Nice, but not worth $15.  I'm sure you plan to add more into this system but as of right now I can't justify the price in the slightest.

Nonetheless, this does look pretty cool. About time somebody remade that old workshop addon, since it was more than a tiny bit buggy. Seems overpriced, GLWS nonetheless!

Regarding the addon itself though, one thing; Glancing at the screenshots it seems to imply that a double door can have two seperate level locks which feels.... Stupid. That's not how locks work, you lock one door and both are sealed. Having the option to have a lock on both seems redundant (And I wouldn't be surprised if users don't even realise you're meant to have two locks, since in standard DarkRP, locking/picking one door generally effects both.)
