To ignite bugs, you must point your magnifying glass beam and hold it steady over them. Keeping the beam focused heats the bugs until they smoke and ignite. If you drift, the target cools down, so maintain steady aim to ensure successful ignition.

As bugs begin to heat up, they panic and attempt to escape the light. They will accelerate, jitter, and break in every direction. You must catch them quickly before they bolt to successfully ignite them and maintain your combo chain.

You increase your multiplier by igniting bugs in quick succession. You must ignite another bug before the combo bar empties. If you miss a beat and fail to ignite a target in time, your chain multiplier snaps back to 1x.

Sparks are earned through every ignition you perform during a round. Once the round ends, you use these Sparks at the upgrade tree to purchase improvements like raw power, a bigger lens, a hotter beam, or faster cooldowns for your magnifying glass.

You can choose upgrades that make dying bugs explode to torch nearby enemies, split your heat ray toward the nearest survivor, leave a burning trail across the field, or turn ignitions into spore clouds that stop bugs from cooling down.

Tier Bosses arrive when the round meter maxes out. Each boss presents a unique challenge. By defeating a Tier Boss, you permanently unlock the next tier of enemies, which will then appear in every subsequent run you play.

Arcade mode focuses on climbing tiers and building loadouts. Hard mode, unlocked after clearing Arcade, features a shorter clock, halved Spark payouts, and bugs that move faster, hit harder, and run wilder, making the game significantly more challenging.

Zen mode is a relaxed play style where every upgrade is maxed out from the start. There is no timer and no consequences, allowing you to use a fully-powered lens to vaporize a screen full of bugs without any pressure.

Grabbing a mid-round drop can trigger various powerful effects. These include slowing everything to a crawl, overcharging your beam for increased effectiveness, or triggering a Solar Flare that causes the entire screen to ignite at once.
Based on source 1.
You can trigger cyan-hot critical hits that shatter bugs. These critical hits provide bonus payouts and cause the screen to shake loose, adding a visual flair and extra rewards for your precise beam control during the heat of the action.
