This is the game I was playing in the last video. I referenced Blue Fire but that was also a fairly small game so I’ll link it here too. It’s worth a playthrough but going back after Pseudoregalia really shows the difference in game feel. Blue Fire is a lot more floaty. Both because you can stack up to four jumps but also because jumping tends to keep you in the air, leaving you slowly falling rather than accelerating to ground as is typical. By the time you hit the later challenge runs you spend more time off the ground then on it. It’s fun in it’s own way but it tends to have sudden turns that force you to quickly snap the camera to a direction and try to figure out the path forward while still engaging in challenging platforming. It guarantees at least one death per segment but at least they added checkpoints after release. Compare that to Pseudoregalia, which guides you through it’s environment and tends keep the path forward visible until you hit the ground.
Both are worth playing and if you’re interested in the design of platformers I would suggest getting both but if you can only get one then Pseudoregalia is the one I would recommend.
