I play a lot of different games like rpgs, arpgs, soulslikes, survival, horror, fps.
I think a progression system or a goal to aim for would add a lot to your game. Perhaps a better score system instead of just adding to the timer. It's not that I had a bad time playing, it's just that there isn't much incentive to keep playing for more than a minute although short playtime is usually good for a game jam.
