The original (and especially the sequel) are horribly dated. Stuff like pointless vehicles with unorthodox controls (like the submarine in the tube level - the only way to brake is to release the gas, turn the exhaust wheel the other way, then accelerate again), random gameplay shifts that worsen the experience (the painful 15+ minute long intestine level with lizard jim comes to mind) and proactive design (some enemies will hurt jim within 0.5 seconds after spawning, like the dogs in the junk level) This is another Yooka-Laylee situation waiting to happen.
But even if I see improvements in that regard, I'm still not going to support it for obvious reasons.
