I wanna fly the Kite
In this game, you must colect items in a sorta-of-open world in order to unlock new maps. How do you know where should you go next? Just look for the only path that you can get through at the moment. Some maps are probably more hidden than they should be (Gray area is a good example), but it's possible to find all of them with some exploring. Also, the open world is fairly easy to get through, and gets even easier when you get some specific items, so you can explore as much as you want to. And as a last resort, if you really don't know what should you do next, you can always check the walkthrough file, but I wouldn't recommend that, exploring the game is half the fun.
The items have multiple functions, sometimes being only useful to unlock areas (Like the fire bullets), and some being very helpful to assist you through the platforming (Like the dashing boots).
The level design is also amazing. Interesting jumps everywhere, the maps are all very well-placed, every single stage feels like a real stage, everything is where it should be. For the most part, as I said. When you get the last item, the dashing boots, the game starts to get boring. The boots are very fun to use, but it gets repetitive after a while. And you'll be using them for 3 stages in a row, which makes things far too repetitive. And the jumps are always the same, over and over and over, their shape might change, but their nature is always the same. There's absolutely nothing new through these last stages.
Visuals are very good (The game uses the standart spikes, but they don't look bad here), and musics are nice. There's no boss, and I still don't understand the game's title (Happens almost everytime).
Overall, it's a very good fangame with a very unusual concept (For fangames). It might get tedious near the end, but that's just near the end, you can stop playing there, if you want to. Also, I feel like it could have been a lot longer, with a bigger amount of items and more gameplay variety. But it's already good as it is. Would recommend.
