Certainly wins a lot of points for me in terms of presentation: definitely made a great first impression with the visuals (although I'll admit that might be due to nostalgia and such, haha). And while the game does start off a bit hard by frontloading with a lot of obstacles and not much direction on how to play, I found myself getting into it and enjoying myself.
Having said that, though, I felt like gameplay was a bit of a mixed bag. On one hand, I thought the game was fun and challenging, despite the simplicity of the mechanics. Flying around, dodging obstacles, conserving stamina, finding a good route, and so on made for a fun mix that kept me engaged. However, I felt it was a bit clunky in some respects. For example, I wasn't quite sure where or what I was supposed to be doing as I didn't know what items to collect and whether they mattered, and there were a lot of paths to take as well pointing in all sorts of directions and I didn't know if there were for story progression or just bonus challenges or whatever. Also, the hitboxes for enemies seemed way too large and the egg seemed too easy to crack from falling the slightest bit, leading to a lot of frustration.
I definitely feel like I still had a positive experience despite the rough bits and I plan on coming back to this to complete it, so well done!
As a side note: I had some real issues with using a controller for this, as for some reason, despite the up key being the key to fly up on keyboard, my controller expected me to press down to fly up. Wonder if it's because I'm using a ps4 controller instead of the more standard xbox controller? Weird.
