Making a good video game is difficult, we can deduce from the existence of innumerable not-good video games. Making five good video games is a rare feat for any developer. Concursion boldly tries to smoosh five together into one single game. It does not really work for any of them. It’s an interesting idea though, so you may want to give the demo out now a go to see what it was trying.
See, Concursion has a platformer, a shoot ‘em up, a jetpack game, a stabby ninja platformer, and a Pac-Man-y maze game, sometimes all on the same screen. Levels have little rifts which pull you into pockets of another genre, so your ninja might hop up and enter a shmup, briefly becoming a spaceship blasting away, before dropping down into a maze to eat dots. But none of these individual subgames are fun.
