Should I try to salvage this old game?

I started making this game in 2019 and stopped development in late 2020. Since then everything in the game started to break. What once was a decent game started becoming a lag trap. It uses the older version of my game engine (which is super buggy) The game also had one of the worst dev processes in my career because I ended driving the 4 concurrent players I had away due to memory leaks early on.
Should I try to re-remaster the game or leave it to rot for another year?
