How many replayability elements are enough?
I'm making an arena shooter, but it's really short, so I spent a few months adding some replayability elements. So far I implemented a few unlockable characters, meta-progression upgrades, unlockable weapons and some kind of level-up system which unlocks new bonuses on arena (like breakable boxes with healing items). Now it feels like there's a lot of things to do, but... At the same time I can't even call it a shooter game anymore - now it's all about replaying the same levels for the sake of unlocking new stuff! It is completely different from what I intended in the first place and now I have no idea how to revert things back without removing all that content I spent months on.
Should I just remove some of the replayability elements and call it a day? Or are there other ways to make the shooter game feel more like an actual shooter?
