I just played the game straight through the to the furnace level. I haven't came across any audio problems, very little issues visually and everything seems to control fine. I can't complain really. No, I didn't install a fan patch. At this point, I don't think it needs it. Works just fine as is.
Chuchel is an adorable little problem solver game. It's pretty basic and quite easy for the most part. I think it is safe to say that fans of Bulb Boy will definitely enjoy this. It is simple, it is charming, it is cute and is quite funny. Be warned though, it is pretty short. My big problem with this game is the changing of the character. Originally he was an adorable little black fur ball. Unfortunately, some mentally challenged white knights have deemed this to be racist and the company has changed him to orange. Now, he does not have that adorable factor anymore. He looks less like a twisted smiling puppy and more like a piece of mould found on a forgotten sock stuck behind your washing machine. It's a bit of a shame really that the developers are a bunch of cowards. This is a nice little experience otherwise.
I just played through this game and found it to be awfully bland. The game's combat is remarkably simplistic in a very bad way. Enemies have a further reach than you and can even pull off moves faster than you. This results in a lot of frustrating fights, especially against enemies with spears etc. I also found that I could be stun locked into place, which isn't cool. There are no save points or any warp gates to help you get from point A to B etc. This means there's alot of running around and back tracking etc. It makes the game extremely tedious. The positives are the story and the music. Both are very well done and really go well with the mood the game is trying to provide. In fact, if it wasn't for the story, I would have turned the game off long ago. Unfortunately, GOG's release of this is very broken. Much like the previous game in the series. You have to limit the framerate with some app just to get the ability to walk working. It's a bit sad really. If my experience is anything to go by, this game series should have never been released on GOG and instead, should have been fixed up properly. Fans of the game from its day will obviously love this. But folks without those nostalgia goggles may find a lot more to dislike than you'd think.
