My game DON'T DIE is one of my most popular projects but there is something that is missing. What do you think it is?

Reported to be moved. This subforum is for suggestions and suggestions only.

I'll move this over to the Project Ideas section for you - that's a better fit for this kind of topic

If you still need project ideas for your game, here's what I would kind of suggest:
Maybe an indicator where the monster or enemy is at. I don't think the player is willing to wildly guess where it would be at so maybe a ghost indicator (like an indicator while using ghost effects)
You could also make the difficulty a lot easier in the beginning unless you are making a very hard game

good idea MrDrProfessorRadical
