Hi, thank you for taking the time to play the game and give us this in-depth feedback, it's really appreciated!
We'll work to make the game more intuitive and, as you suggested, to explain better some things that a new player may find ambiguous or hard to get.
Regarding controls you are right, when they are inverted it can get a bit confusing or even frustrating; we still have to find a more solid solution for it.
As for the level design in general there are some issues to tackle, we had to put our best in a short time (the game has been developed in about 3 months and not on full time) and it has a lot of room for improvements. Can you expand a bit more your suggestions on level 13 and 15 please? I'm not sure to get exactly what you mean. The level 22 has to be reworked a bit since it can be mechanically frustrating, you're right.
We also have to add some kind of video settings and compatibility for other resolutions, thanks for pointing that out.
Again, thank you for all the feedbacks and the compliments!
Have a good day :)
