Need opinions to improve MainComplex
Hey I recently released my Destiny inspired ROBLOX game a few weeks ago called MainComplex. I need to gather some critical opinion data from others to make strategic changes to help the game to be easier to understand and more fun to play overall. the game in my opinion is already well developed and polished. 3 people work on this game including me and we have a small dedicated player base but the drop off is pretty big for this game which is holding it back from advancing.
Do not sugar code anything. If something needs improvement tell me. I would much rather critical feedback! 
I’ve already tried adjusting the UI to be simpler, change their spawning location from the tutorial straight to the lobby (we saw the biggest drop off) to them going straight to the action which was a mission in the mission’s playlist. (Helped the drop off but not really) I feel the game is really simple and easy to understand but it seems I’m missing something critical.
