The trees are actually fairly easy to avoid if you're a good pilot, and if you can't, it's always possible to fly over them and avoid the issue entirely. It's just a matter of if you're able to fly through them, you can get up to much faster speeds and thus complete laps faster.
I would just prefer if you got some time beforehand to get used to the plane controls again given that it's the only plane map. Some simple turns and straightaways. That way when you have to deal with the trees it's a nice difficulty ramp up instead of being a constant course element the entire way through. It also makes the trees more unique, and more thought can be put into their placement if they are delegated to one specific area. This also serves to make the course itself more memorable and exciting; it feels like a journey that ramps up with its own obstacles at each section.
Also, while the superkarts actual speed is fine the lapped design of the courses is unfortunately a little boring. Each course seems to overstay it's welcome quite a bit. I'm not too sure what the cause of it is but something should be done to help with the overall flow of the races. The biggest offender of this was the (very impressive build wise) snow track. The courses just feel like they drag on a bit as there's not really much that's very challenging. Racing games (specifically the cartoony kart racing games this is trying to evoke) use powerups to help break up the flow of the track, but I'm not too sure that's a solution as those racing games also offer things to compliment those as a design element, which this gamemode lacks such as areas of courses that slow you down or speed you up.
As it is if you get into first place and know what you're doing then there's really not that much stopping you from winning, much like the original speedkart. This can be compared to Trackmania, but Trackmania is built around time trial based gameplay that demands perfection with quick resets to keep the game flowing, with no collisions on other players cars and simple point to point races.
Superkart seems to be deliberately aping a kart racer, but unfortunately doesn't bring much to the table besides the cool kart customisation, well built tracks (although built around a rather barebones design) and a original soundtrack. To be fair, that's already better than speedkart has ever been, so as a sequel to that, it's definitely an improvement.
Perhaps it is my own fault for thinking this would be anything else and getting my hopes up. It's worth considering how many of the negatives I listed can also be found in the speedkart gamemode, too. As it stands I would probably rather play superkart because as long as someone finishes the race then you progress as opposed to speedkart where people can just sit around until they run out of time, holding everyone up.
Edit: sorry if this doesn't read great. I just wanted to keep adding onto this post with stuff that reflects my time with the gamemode so it's kind of ramble.
