A multiplayer game is a hard feat for a one hour and a half game. The game had some networking issues, maybe next time refine the multiplayer first, before stepping into the rest. Try maybe to start next time with a 2D project as its much easier to manage in this time frame, also I think you might be using a template off the unreal asset store, it would be good for your programming skill to at least use the code you wrote yourself. But good luck on your next game, I wish you the best, maybe try a smaller project first.
