Archfoe is a pretty visually unappealing needlegame, not so much because of the sprites but more so because of the spike layouts. The game has three screens and they all look like someone closed their eyes and started randomly putting spikes and blocks around.
The level design mostly follows one simple device: take ordinary and commonly occuring jumps and squish them. You have the squished diamond save, the squished sideways gate save etc. And the saves are often just that, one or two ultra-precise jumps and nothing else.
For me there really isn't much to gather here. The design isn't your typical generic needle where the same jumps are just rearranged in different orders. These jumps are very prevalent here absolutely but at least there are a couple of interesting configurations. My problem is more with the extremely grindy nature of the game. Sure, it's something you can expect going into this type of needle but so many of these jumps are simply of the kind where you don't improve at them at all.
