Game is unique, decent, although needs more work on balancing the platforming.
The environment, sound design, character animation, flawless, truly interesting and addictive, yet, the platformer part of the mechanics is not balanced as well as it could be. I completed the game, the first round, I guess and it took me some time.
My personal advice as a game developer, balance the platforming a bit more, make an end sequence, maybe something like a door or gate, addition to that, making different levels would be better. Start with something simple, like making 1-2 platforms and then extend on it. This one level looked like the boss level, if you know what I mean. In my opinion, adding more, easier levels will build up to this and it would impact the player more.
Good Luck on your future projects!
First of all, thank you for making such a unique game, I enjoyed it really. The unbalanced difficulty was concerning the huge arena, yes. When you have platforming like this, you just have to start with basics and then expand on the idea and make it more difficult, it's just how games work, nobody wants to be thrown at something huge in the beginning, but, that's just subjective, I guess. The best part of the game is the platforming and overall idea.
It's just my opinion, but maybe you can make something harder, even more and let this "part" of the game be in the middle, like something simple, then this and in the end even more difficult. It's your choice and your game. Thanks again for creating it, I really had fun!
