Here's a game I got in a Humble Bundle back in 2013, played it for a while... and left it halfway for no apparent reason. Yeah, I do that a lot... :\
And though I don't remember exactly why, I'm sure I didn't quit it because of a sudden difficulty spike or anything of the like, as this game's difficulty curve is pretty well crafted. If anything, it probably leans towards the easy side. Well, the normal mode certainly does, whereas the alternative mode is noticeably harder: the levels are very similar, but the small differences in them are enough to severely complicate your progress. After beating the regular mode (bonus level included, after I realized the sub-level selection screen told you in which ones were the secret stars hidden) I tried a couple of levels from the alternative mode... and I gave up, this time for real. I've got a huge backlog and I sincerely think I've already experienced everything this game has to offer, so I don't really want to know whether rage and frustration is also part of its menu.
To those who don't know it, I'll tell you NightSky
is a simplistic but beautiful 2D platformer developed by Nicklas Nygren a.k.a. Nifflas (of Knytt
fame). Beautiful because it's got some of the prettiest 2D graphics achievable with a monochromatic foreground over a bunch of slightly more colorful backgrounds, and simplistic because its controls are quite simple: left, right, and 2 ability buttons. It doesn't support gamepads (at least the Linux DRM-free version from Humble doesn't) but, in hindsight, playing it with the keyboard is probably the best option: sometimes, in order to pull some maneuvers off, you need to switch from moving right to moving left almost instantly, and that's way easier to do with a keyboard than with the analog stick of a pad.
Digressions about control methods aside, I quite enjoyed this game from beginning to end. I said it's a platformer, and I stand by it, even though the main character is a crystal ball that cannot jump, so you'll have to rely on slopes and ramps to reach higher places. But there's only so much you can do with slopes and see-saws, so thankfully you also get to drive
a vehicle (or to pilot
a makeshift aircraft) from time to time. Some of this "vehicle interludes" may feel a little far fetched or out of place, but overall I think they contribute positively to the level variety and my enjoyment of the game. My list of finished games in 2016
