Blade Rush is a challenging platformer with "stealth" elements by Darren Briden, and the reason I put that word into quotes is because while the game involves trying not to be spotted as you navigate levels filled with enemies that will instantly shoot you to death if they spot you, you kill those enemies by smashing into them at rocket speed like a Tasmanian Devil. Using either [WASD] or the [arrow] keys, just run and jump (and wall-jump) around levels, using the green sphere around you as a visual guide to let you know when you can hit [K] to hurtle yourself onto him and render him a bloody smear with the sheer force of impact. Which, you know. Whatever works. Finish stages as quickly as possible to get better rankings, and avoid being seen! If an enemy is alerted, they'll kill you in a single shot... and as you play, you'll find even more hazards to watch out for.
Blade Rush is sort of unexpectedly hilarious and fun, and I say "unexpectedly" because at first blush it's a very sparse and simple game. The visuals are itty-bitty and grey, and the level design doesn't offer a whole lot of variation, aesthetic or otherwise, consisting mostly of different configurations of platforms and hazards floating around. Where it starts to shine is once it takes the training wheels off, and you realise you can start triggering attacks in midair and quick succession, zipping around like a tiny murder-rocket, and using that velocity to carry you over otherwise insurmountable gaps and around obstacles. The trick is figuring out the best order to eliminate foes to do so. It eliminates what initially looks like is going to be a lot of wall-jumping and landing on miniscule platforms... though there is admittedly still quite a bit of that to be had at times. It's sort of a simplified, less cinematic Vox Populi, Vox Dei. Though it lacks a lot of variation and might be still too fiddly for some players, Blade Rush is still a clever little game with a lot of minimalistic style that would be great to see expanded in some way in the future.
