In Downwell, your goal is to descend as far as possible while surviving enemy encounters and collecting red gems. Use the Gunboots to shoot downward, which slows your fall and damages enemies. Land on platforms to recharge your ammo, and prioritize combos by chaining kills without touching the ground to earn extra gems, health, or charge points. Visit shops to buy health or ammo upgrades, and choose upgrades wisely at the end of each level to suit your playstyle, such as increasing health or improving firepower.
