Hi clansing, first of all I wanted to thank you for your comment, people's opinions help me a lot to improve when creating games.
I would like to talk about level 40, now playing it again I have seen that as you say it is quite heavy and slow, and I wanted to let you know the meaning of this level, as you have seen that there are several levels that are references to major franchises in the world of video games, and in this case I intended to refer to a level of The World's Hardest Game, but, I think you're right, and it breaks the game quite a lot.
I also want to inform you about the reason for the moving blocks: first I want to clarify that this game was created by one person, and it's the first game I make, so when I created the levels I didn't want them to become too repetitive and that's why I decided to add this mechanic, to give more variety to the game and make it a little more difficult, it's not for lack of ideas, in fact I wanted to make 100 levels, but the people around me recommended me to make 50 and if everything went well, to make more.
And finally about the bugs, I'm aware of it and I'm working on fixing it.
With all this, I wanted to thank you for playing the game, I hope you enjoyed it except level 40 and also thanks for commenting.
