Prioritize leveling if you want to survive
Leveling is important because it is the fastest way to earn upgrades and better weapons. You’ll want to keep your damage high if you plan to stay alive for longer periods. Collect those gems and don’t wait too long to level. Also, don’t sleep on the crown 👑! As you survive for longer durations, experience gems give you less bang for your buck and it’ll take many more of them to level up.
