Hello,
We are glad that you played and liked the game!
Your criticism is very valid. A game this massive needs more art and variety of background and enemies to make it more compact. Otherwise it can become overwhelming.
I sincerely encourage you to finish the game. You still have the second half of the map to discover. Platforming is a bit more challenging there, and you will acquire abilities such as riding on those wind tunnels, and also Teleport. I think you will like those mechanics.
There is also a sequence break to get Teleport earlier, in case you get to find it.
The boss battle also asks the player to use his abilities. I hope you get the opportunity to see the rest of the game.
Thank you again for your time,
Cheers
