Finished Olija. Look at that, I played a game from 2021 in 2021.
Pretty good. Throwing the harpoon and zipping to it is a lot of fun and the mechanic is seamlessly worked into every aspect of the game - platforming, combat, puzzles. And it peaks around the time they introduce a sword you can plant in the ground and zip back to it same as the harpoon. Combined they more or less create a portal gun (the weapons are even colored orange and blue), great for bypassing puzzles.
Just wish the gameplay would escalate along all the cool ideas the game brings up once or twice and then drops. I was waiting for the difficulty to ramp up and hit a level that would demand a choreographed mastery of all the mechanics, like those rooms in Guacamelee that have you running up a wall, flying across the screen, going in one portal and exiting another, doing a body slam while shifting between realities, performing a dodge roll across an obstacle, doing an uppercut to gain height, headbutt a block and punch forward to land safely. All in one single motion, all in one ROOM. Olija doesn't even pretend you have to be all that good at the game, despite the complexity and versatility of its mechanics.
