Custom / Concept, by 
Firstly, always include the tileset with your upload. Although Coolday is a common set, I didnt have it in my TSF folder and had to get it from my 1.23. Although this doesnt affect the rating it gives me somewhat of a negative view of the upload, which could potentially indirectly affect the rating.
First obstacle already. Powered up RFs are much worse for wallclimbing than normal ones, bleh. I wasted all my powered RF ammo and got the norm from the crate nearby so it will be easier.
Past the part where you get stuck in a wall and go through a tube, you can get stuck in the diamond shape tiles you put in very easily. There is a warp to get you back, but you’d have to slide down the lower wall of the triangle to get to it. I almost didnt notice it. Instead of placing bugs so you can fix them, it would be better to just not place them at all (ex. a square instead of a triangle could’ve prevented this, among many other possibilities, some which probably would’ve kept the obstacle of climbing diamond edges unchanged).
Next come spike balls. I dont remember whether or not they can kill you in treasure, but they’d either be a major nuisance if they did, or barely an obstacle if they didnt. (By the way, Im assumin you set the game mode as treasure, as the author gave no information about that).
Then comes more RF climbing. Yay. Nothing interesting either. After that comes running in darkness, which was actually mildly fun for me in my bored state, but anyone could just turn the lighting off at any time to make this easier. Following that is a lot of pointless running and jumping which anyone can do. Next part is slightly amusing, with flashing blocks you need to run by. So far my favorite obstacle as it’s at least sorta original. Sadly after a while those flashing blocks can give you a headache. You could also skip most of it quite fast if you just jump out and run on top of the blocks instead of through the passage they form.
Finally, the level ends. This is definately not 8.5, for the reasons I’ll state below.
Gameplay. The obstacles weren’t new at all, nor were they entertaining. Except for the RF part anyone could win these, which wouldn’t be so bad if it weren’t for the RF part because those people would be able to beat anything except it. Running and jumping all the time got boring too.
Eyecandy: Well, first the positive. There aren’t any extremely noticable tilebugs, but that is because the author used 1×1 tiles everywhere. Except for the snow which itself doesn’t look great,there is basically nothing to look at in the level. Not even layer 4 eyecandy.
Music didnt fit much at all either, I found it kind of weird that medivo music would be in a level using such a happy bright tileset.
Overall, this level was long and monotonous. Didnt throw anything surprising at you. If the author him/herself admitted the level is long and stupid, why did they upload it?
Final Rating: 5.5. Definately not a download reccomendation, nor deservant of its currently overrated 8.5.
