I get the intension behind having a higher difficulty, I do struggle not making my games hard aswell. But there are some issues with this.
1st you don't give the freedom to explore and find your own way of playing, you having to tell me exactly what you did in the first couple second of your game kind of shows that. Having this kind of exact pattern to follow can be great, don't get me wrong! But if you don't build up to it, by giving the player some time to enjoy and exlpore on their own, they lose motivation more often than not.
And 2nd the player does not know everything YOU know about the game. I have no idea about the bombs walking speed, explosion range, damage or walk speed. Neither how long I have to charge to kill a bomb with one shot. All of this things I can find out by getting some easy introductional levels, to get me up to speed.
In the end it's your game and you can do what you like, but it is a shame if people only see the first 10 seconds of something you have worked so hard on!
