It is, but it’s also really buggy. And there’s a lot of platform jumping later on and I really dislike it.
Which is unfortunate because I feel l like the game actually feels pretty good in the first couple of levels but you really start to notice the flaws pretty quickly and it feels like a chore to play.
The weird thing about this game is that while I don’t think it’s very good, it ended up being a pretty important game to the recent retro fps revival, because a lot of those people went on to work on far better games or start their own studios, like New Blood who made Dusk and Amid Evil.
