I tested, and I like, but for the moment I am blocked.
I have just recovered the map level 3, and the double shots, and the path does not seem clear to me.
Either there is a lava lake that is too big to jump (not want to jump to see the result) or to another place the platform is too high even for a wall jump. And I do so much backtracking that I'm afraid to go back on my steps xD
In short, the game requires a minimum of exigency by location in (platform term), and the bosses, for the little that I did, does not represent a real threat.
The game is good, but what I would absolutely need is an option menu, at least for window mode or sound adjustment. There are many possible improvements, but it's up to the creator to add them;)
( sorry if my english is bad, i prefer the french language ^^ )
