Laser Beam Challenge vs Neverstill

Laser Challenge is a puzzle game where you have to destroy a crystal with a laser beam. The beam can be blocked or deflected by various obstacles present on the screen. You must use the objects on the board to solve each level. There are 6 levels to understand the rules in the tutorial. Then there are 10 free levels of increasing difficulty. Finally it is possible through an in-app purchase to unlock 25 additional levels which are also increasingly difficult to solve.

Fly the drone above the train and defend it from all the monsters trying to wreck it. The armoured cars fight on their own. But you are the thing that can support them, and you can only be in one place at a time. Fly the roof. Overcharge the car you are standing over. Stomp the boarders off the deck. Drag in the scrap and upgrade the cars and drone at the stations. TWELVE WAVES TO A TERMINUS the line asks how long you want to keep going. Pull in and bank the run, or run on into the next division, where everything that was hard is worse. There is no last stop, only the one you chose or lose. THE TRAIN Laser, mortar, tesla, shield, flak, carrier. Three of a kind in a row unlocks pierce, chain, salvo and reach. Three of a kind anywhere can instead be fused into one car a level higher, a railgun, a jericho, a gatling, which costs a single coupling instead of three. Breadth or depth. You cannot have both. THE DRONE Whatever car you hover over fires harder and faster. Scrap only magnetises to where you are. Boarders only come off under your boots. Nothing you do is free, because everything you do is somewhere else. THE STATION Goods on plinths, a board shows what a repair costs, and a lever marked DEPART sends you back out. Buy a car. Bolt a module to it. Decide what the train is for. THE DEPOT A dead run still pays. Bonds buy the shape of the next run, never power inside this one. A warranty costs thirty and buys you a single derail. After that it is percentages. WHAT IT COSTS Free is the whole game: every wave, every car, every module, the depot. A couple of the cars and modules are earned by playing rather than handed over, and none of them are for sale. The Line Pass is one optional purchase. It clears the hoardings, opens the difficulty ladder past the first line, and unlocks the deeper depot ranks. A one-time unlock, not a subscription. Nothing behind it changes the balance of a free run.
