Playing Haste
Self-described as a high-speed third person running game, it's a game all about building speed while dodging obstacles as the world collapses behind you. It's sort of a blend of the boost sections of modern Sonic but with the momentum-based gameplay of classic Sonic. You run automatically, leaving you to focus on steering around obstacles (including in the air), launching off hills and hitting your landings. And you want your landing angle to be as shallow as possible, preferably on a downslope, because that increases your speed. Hit something or land on an upslope, your lose speed. The goal of course to reach the end fast and smoothly without hitting anything and collecting as much of the ingame currency as possible.
The game is structured in a pseudo-roguelite way of 10 shards/worlds where you have to choose your path through a number of randomly generated stages of various types: regular running stages, rest spots where you can meet the various characters, stores where you can buy temporary upgrades and consumables, and extra hard challenge stages to earn temp upgrades, ending in a boss battle. Beating a world earns you a second currency you can spend on permanent upgrades. Overall, the basic gameplay is enjoyable. Blazing trough a level at breakneck speed while narrowly avoiding lazers and pits is quite satisfying, thanks to smooth controls and liberal air control. To bring it back to the Sonic comparison, at its peak it plays like what Sonic fans have been saying they want for a long time.
The problem is that its bag of tricks is pretty small. There's really only one terrain type and like a dozen obstacles, the temporary items only provide small increases to stats unless you get lucky enough to be able to stack multiple of them, and I've only encountered two boss types. The randomly generated nature of the levels also means there's no real difficulty curve, and certain combinations of obstacles can make some stages much harder than others which come way later. It means that despite there being 10 worlds, you'll have probably seen most what the game has to offer by the second one.
