Skins, new missions and difficulty

Hi everyone, before I continue, you should try out the game to have a resemblance of an idea of what am I talking about. You can play it here.

It was a long time since my last update, I didn't have time for working on the game that much, but enough with the lame excuses.

When I saw people playing the game, many picked it up for a short time and then left it without even experiencing a tenth of it. I really wished to change that and create a gripping experience that people would like to finish. So I decided to add skins to the game for each character that will change as the player progresses.

 (I am not that good of an artist, but I think I am starting to get better)

A lot of people said that the game is too difficult, but I am not sure how to handle it without ruining the gameplay. One possible way is to make a new boss that will hopefully ease out the difficulty curve. And make the player more ready for the rest of the game. Another can be making some of the attacks in the beginning easier. Or maybe something else. 

I will be glad to hear from you about more possible solutions for this. As well as the point where you got stuck, what attack was too hard for you, or maybe possible attacks for a future boss.

I added 2 new missions for the third boss: one is to beat it without getting hit, and the other is to beat it without dashing.

There is a new item that drops bombs on the platform that deal damage when contacting an enemy.

Anyway, I think that is all for now. I am not sure I covered everything because it was such a long time since the last update. I wish you a good day, and please tell me in the comments your thoughts and ideas.
