I have just published my first ever game and am looking for some constructive feedback! I learned a lot while making it and got over my initial fear of scripting. 
Here is the link: Ultimate Blox Jump - Roblox
I was also wondering what the best way to get people to play is? I have already made a few ads but they don’t seem to be doing much. Thanks!
Hi,
The UI in the game looks great. Though, I’d make it so only one pop-up can happen when the max amount of blocks spawned is reached. It can fill the screen quickly, maybe that’s the intent. 
The game isn’t what I’d play in my free-time, but it was enjoyable. It would be a great multiplayer game to play with viewers on a livestream. Maybe you should reach out to some people on Twitch or YouTube who do Roblox livestreams.
I found that watching how other people play my games is helpful. So, here’s a video of me playing the game. It might give more insight on how/where to improve things:
Thank you so much for the feedback and video, it is very helpful! I agree that this is more of a passive game for hanging out with friends or simply when you want something to do when you’re bored. And you’re certainly right about the popup—it can quickly fill up the screen. I’ll try a fix for that soon.
Again, thank you for the feedback and taking the time to film a playthrough! It’s very cool to literally watch you playing the game.
