This is legitimately one of my favorite platforming games, and it's very fun and entertaining. Edmund wasn't ~amazing~ at making games yet, and it shows, but there's a lot of value here. The level design is cool (most of the time) and the music and stuff is all nice. Controlling Gish was quite fun and once you got the hang of it you could get him to do really neat things. You could throw enemies across the screen, do really cool parkour-esque platforming and tricks and stuff to get through levels quickly.
You've got to look past a few flaws, though. The unique platforming mechanics are hard to get used to it's turned many people away from the game, keeping them from giving this more than an hour or two of attention. I understand this. It's not a game for everybody. It's not rewarding enough for most people to warrant all of the trial and error, I think. Despite this, It's one of my favorite platformers and I love it.
At least, I used to love it.
Gish was recently updated. The achievements are now working, which is cool, but the game itself has gone completely to hell. You can now instantly kill yourself by moving the wrong way, or by squishing yourself against the ground or a rock, or by moving too quickly through a tight space. I've recently been playing the game for like an hour and a half and I killed myself dozens of times. Right now, the game is a ♥♥♥♥ing mess and it's almost unplayable. I don't know if Crypric Sea are planning on fixing this or not, but as of right now, this game is terrible. It's a shame, because I really loved it a lot. If they fix the engine to where you aren't commiting suicide every 15 seconds, I'll change my review and I'll most likely play the game again and enjoy it thoroughly. Until then, forget about it.
