Thank you for liking our game..we know about the problem where sometimes the obstacles completely block the player, which is caused because of some flaws in the random generation algorithm. We are working on a better algorithm so the bug doesn't occur anymore. A tutorial level we thought of adding but didn't got the time as the game jam was close to ending but we will add it in future.
I completely understand you. In another jam, me and my friend had only time to do either tutorial or fianl boss.We decided to cut out the tutorial . Most people didn't even able to finish the game to see the final boss. Tutorial is really important. Even a simplest one. We learned that the hard way. Sorry I'm acting like a teacher but I'm just trying to give some advice one developer to another. :)
