Your game definitely have a better difficulty curve. Having played my game for a week I wasn't good in estimating the time needed to learn the game in the first level and haven't the time to do some testing with other people.
Adding an interactive tutorial is one of the thing I tell myself to do every game jam but in the end I don't have the time to do it. I totally need to learn how to do it.
Figuring out the keys was intentional. The hints appear after a couple of seconds, so if you know how to do you can do things faster. That was our take to "just get started"
