Finished (with all secrets found)!
This was pretty cool!
At first, I thought it was a bit small. But then I got used to size of elements and I've got a lot of fun discovering new objects and find all secrets of the game. Dragon's fire is brutal, and it gives a good oppression feeling.
There's some tweaks to do about the platforming physics and sometimes the timing with dragon is a bit short. Despite all this, it's a good entry and there's a lot content.
Good job! :)
