The four-tool loop, hotbar controls, upgrade priorities, and what Coins and Gems are for in each run.

Finish It! is a construction simulator from Moonrise Interactive where an unfinished building has to be plastered, smoothed, plated, and painted surface by surface. Every action pays out Coins, and Coins buy upgrades that make the same actions faster. The whole game is one repeating routine with four tools, so once the routine clicks, the only thing that changes is how quickly you can run it.

Quick answer: Hold E at the mixer to fill your sprayer, spray the highlighted area with the left mouse button, switch to the trowel to smooth it, hold E at the plate supply to grab plates, place them on the smoothed patch, then equip the paint roller and paint them — repeat until the project is done.

Tools live on the hotbar in a fixed order, and the number keys are faster than clicking. Every tool is used with the left mouse button, either as a tap or a hold.

How to finish a surface: the seven-action loop

The tutorial walks you through this once, then leaves you to repeat it on every wall and floor in the stage. The order never changes, and skipping ahead does not work — plates will not sit on plaster that has not been smoothed.

Walk to the mixer and stand next to the plaster bucket. Hold E until the fill meter completes and the “Bucket filled” message appears. Your sprayer is now loaded.

Head to the highlighted section of the build and aim at it. Hold the left mouse button to spray plaster across the marked path until the highlight is gone. The result is intentionally uneven, which is what the trowel is for.

When the sprayer runs dry mid-patch, go back to the mixer and hold E again. Early on this happens often, because starting capacity is small. Return to the same spot and finish covering the highlight before moving on.

Press 2 for the trowel, stand close to the sprayed patch, and hold the left mouse button. This levels out the lumps and blemishes left by the sprayer until the surface reads as smooth.
Press 3 to equip plates, then go to the plate supply and hold E. A counter shows how many you are carrying against your current limit, which starts small and grows with carry capacity upgrades.
Return to the smoothed patch and click to seat a plate. Keep placing until the smoothed area is covered, going back for more plates whenever you run out.
Press 4 for the paint roller, pick your color, and hold the left mouse button over the plates. Painting is the final action that closes out the surface.

How to tell a surface actually counted

Each stage of the routine reports back on screen. Filling the sprayer shows “Bucket filled.” Seating plates increments a running counter such as “Finish plate seated (x3).” A completed plate returns “Finish plate painted!” and Coins land immediately after each action.

If a step refuses to register, it is almost always one of two things. You are standing too far from the object — the mixer, the plate supply, and the patch all require you to be close — or you have skipped an order step and are trying to place plates on plaster that is still rough. Finishing the entire project ends the run with a Gem payout and a screen showing your clear time.


Coins and upgrades: what to buy first

Coins are per-run currency. Every run starts you at zero, so there is no reason to hoard them — spend as you earn. The Upgrades button sits with Paint, Shop, and Rebirth on the left side of the screen, and the tree starts locked behind a single opening node.

Sprayer Power Lvl 1 is the first unlock and costs nothing, so take it during the tutorial. From there the early branches cover Sprayer Range and Sprayer Capacity, alongside carry capacity and movement speed improvements. Capacity is the one that cuts the most wasted time, since it means fewer trips back to the mixer.

Tip: buy upgrades the moment you can afford them rather than saving up. Every purchase makes the next batch of Coins arrive faster.


Stages, Gems, and Sprayer skins

Three stages cover three difficulty tiers, separated mainly by how much surface area you have to cover. Gems only come from finishing a project, and they are spent in the lobby on Sprayer skins that carry passive bonuses into future runs.

StageDifficultyBest for
PoolEasyLearning the loop and the upgrade tree
Storage UnitMediumSteady Gem runs once upgrades come quickly
HouseHardClear-time attempts and larger Gem payouts

Because skin bonuses persist and Coins do not, Gems are the real progression. That makes co-op worth using — surfaces can be split between players working the same project, which shortens the House run considerably and gets you back to the Gem screen sooner.


Paint color is entirely up to you. Pressing P opens the color wheel at any point, so a project can be a single flat shade or a different color per surface without affecting rewards. Start on the Pool, spend Coins as fast as they arrive, and move to the larger stages once you can cover a highlighted patch on one tank.
