It’s good, but I do have some criticism. If you’re looking for strictly in-game feedback, then skip #4 & #5.
Lack of accessibility for Blockate players
If you want to target Blockate players, which you likely do, you should add support for spaces inbetween the generic arguments. (e.g. both !decal size & !decalsize would work) I have seen many Rebuild players commonly use commands such as “!decal color [BrickColor]” or “!text size [х] [y]”, which results in the user color’s headshot being plastered onto the block and the text being set to “size [х] [y]” respectively.
Poor mobile support
While I don’t play on mobile often, when I tried Rebuild on mobile it was very unpleasant to use. This is fine if you usually have access to a computer, but drives away a significant part of the Roblox player base since 80% of Roblox players play on mobile.
Flying is very buggy
When I tried to fly using double jump, I was able to go up with spacebar but I was unable to go down without disabling shift lock. Blockate has solved this problem so maybe you could contact them about how they solved it. Another problem is your character goes up on its own, even if you’re AFK. Here is a demonstration of this, sped up 100x.
“GRID FIXED!!!” has been in the title too long.
Not really a problem within the game, but still a slight problem. I think that that text has been there for too long, and it’d be wise to take it out. New players will not know that the grid was ever broken.
Make a Discord server and link it in Social Links
Again, not really a problem within the game, but a problem with keeping players coming back. If you want your community to be connected and to keep coming back, a Discord server is the best place to achieve just that. Yes, I know there is already the We Sell Machines server but that’s for all of We Sell Machines’ projects, and confuses new players looking for the non-existent Rebuild Discord server.
