Liked what you did here, although I had troubles with getting down controls at first but once it clicked I started to enjoy. 

Very simple but very effective and fun! You used all the mechanics in some way or the other and althouh its not the most original game I would't change anything about it. Except maybe how  the  ground pound thing looks . It's always nice to remember the sweet mix of frustration and satisfaction of playing Celeste.

(I actually like the way double jump works)

Really nice precision platformer. I see a few people say that the last section's difficulty curve is very steep which I don't fully agree with. The difficulty does increase quite an amount at the end, but I believe that it's difficult cause you can't really see when to jump in the few attempts cause parts of the obstacle is cut off screen. Zooming out the camera or having the camera move to a certain position in that portion could fix the issue.

I don't know how to feel about the double jump. The second jump doesn't seem to give you enough height to warrant needing it and could have been replace by having only one jump but with varying heights, depending on how long you hold down the jump button.

Still good job overall.

realy good game, biutiful and fun

i just dont like control like that but you are good for adding keyboard control :) 

the only problem is the key for change direction is the same of falling key when you are in the air

i dont like the design choice of "cant change direction in the air" 

well play for the game :)
