Decent, I suppose. The graphics, physics, sound, and presentation are all very tight, though I think the game could stand to be more difficult and maybe include more features just for the sake of being a good game. Since the game never required the player to perform impossible feats, I never felt very debilitated by the lack of jumping or climbing. Perhaps it would have been better if you had a stamina gauge instead that would drain faster, increasing the difficulty, or perhaps having jump height or climbing/walking speed decrease more gradually. I definitely didn't like that I was still able to run really fast even after my jump height had been reduced so much.
The dialogue is fine but didn't really move me, I think that's pretty much impossible for a game this short. I also want to point out how stupid the word 'cure' is. I'm really sick of people acting like you can just throw money at a bunch of scientists and more money will miraculously equal more progress, even as cancers and autoimmune diseases have been steadily increasing. Obviously we're giving money to the wrong foundations if the problem is getting worse. But enough politics, this is a good game.
