Played the Reignition Project
It's crazy how many of these fan-made ports of Sonic games there are. Sonic must have one of the most dedicated fanbases. But as with Sonic Unleashed Recompiled and Project 06, this is not a critique of the port, but rather the game itself.
I've used the terms "bite-sized" and "linear" to describe Sonic Heroes, but boy do I feel silly now. I'm kinda baffled at this game's existence. It's only a tiny bit more complex than those mobile runner games. Multi-layered level design has always been a hallmark of the series. This game just ditches that completely. Instead most of this game is just one linear path with obstacles.
And every zone consists of repeats of the same short level that you can beat in like a minute or two, except with altered goals, like avoiding orbs or outrunning a ghost opponent. It's basically just padding.
Sonic and the Secret Rings is not exactly a terrible game in a vacuum. But as a Sonic game this might just be the lowest the series has ever sunk.
