I finished the flash game Phoenotopia today, and it was an interesting experience.

First, it doesn’t feel like a flash game at all. It took me over 15 hours to complete it with all non-consumable items, and it has plenty of dialogues.
The exploration feels rewarding and most fights feel manageable (specially if you have enough max hp and healing items).

There are two parts that have a high difficulty spike, though (major spoiler warning):

1) The entrance to Daea’s second tower, with its agility puzzle about dodging arrows from all directions while climbing two ladders

2) The segment after the final checkpoint, with how chaotic the final boss is and how fast the chaser is (btw, check your inventory after the final fight, as it seems the game gives you a honey item; it should help a bunch)

But, all in all, Phoenotopia is a game I’d recommend, just mind the difficulty.
And I’ll probable play at some point the remake that released a few days ago.
