I didn't enjoy them. I wouldn't want them to be cut from following games, though, since I actually like both characters. So here's why I didn't like them and what I would like to change for the sequel:
I agree to EekumBokum202... While the Kartos challenges certainly had flaws, most of the time it was my own fault to fail them. I can't say I had fun failing, though... I was looking forward to Yooka-Laylee because I don't really like 2D platformers and I'm really, really bad at them. The Donkey Kong Country series (incl. Returns 1&2) is WAY to hard for me. Every time I play them I see collectibles which seem absolutely impossible for me to reach and even just trying to reach the end of the level I keep dying and dying - and the mine cart levels were some of the worst for me! I never finished a single DKC game... I guess I'm just not part of "generation NES" where failing at games was normal and supposed to keep you busy for a longer period of time since games were generally shorter. I have a huge stack of unplayed, time consuming games and simply lack the patience to try the same challenge again and again. When I recently replayed Banjo-Kazooie it was the perfect formula for me - a few challenging sections but most of the time a relaxed and fun mixture of exploring and platforming. Having a Kartos 2D platforming challenge in every world of Yooka-Laylee was a little too much for me and it caused me to have that nagging bad feeling that entering a new and exciting world also meant beating another (and even harder - except for world 5 which wasn't SO bad
) Kartos challenge.
So my wish for Tooka-Laylee? Keep Kartos, but don't have him in every single world. Or at least don't make it mandatory to beat him to 100% complete the game. You could also completely drop "challenges" and make him part of the level where you need to survive a Kartos ride once to reach a secluded area (afterwards switching areas should only need you to talk to him).
Again my main complaint is that there is too much of him. 2 pagies in every single world? 15 out of 145? That's a little much of something I don't enjoy. Every time I played a new world I tried to beat Kartos and Rextro first, so I was able to enjoy the actual level afterwards. The mini games had wacky controls and it took a lot of time to get used to them AND to master them. No, it wasn't impossible, even Hurdle Hijinx, but I didn't have fun and it took me a lot of time to beat them. I also wish the mini games had been presented a little more retro instead of ingame graphics, Yooka and Laylee as playable characters and pseudo-retro gameplay. Do you guys know the NDS game "Retro Game Challenge"? () They completely made up their own 8bit retro games which feel authentic AND are actually fun. I think the most important thing is that they also control like real retro games.
My wishes for Tooka-Laylee: "real retro" Rextro games and again not being forced to play them all like a maniac. Maybe give players the choice which games they want to play to achieve a certain score or have a little Mario Party-esque mode so you can fail some games and still win in the end (would be fun for multiplayer as well).
While I greatly enjoyed Yooka-Laylee (I'm almost done now, only missing 2 pagies) Kartos and Rextro were a true disturbance in my personal gaming experience because I had to suffer through 20 pagies for them. I wouldn't mind cheating when I replay the game one day.
