That's the second time I heard that the tutorial was too long.
Wait, where are my manners? First of all, thanks for your feedback!
It's actually a very interesting thing with why there are so many tutorial levels. The way I designed the levels, I tried to always introduce one new idea or mechanic per level. Something interesting about the game itself. Some levels are better at doing this than others. I mean, there are 3 shooting ranges, but they all got their unique twists. Maybe I should have done an exception for the tutorial.
But those are the small issues that require lots of playtesting to figure out, also 'accidental' playtesters like you. If I sit next to somebody, they won't stop playing the game because the tutorial is too long. You can only figure this out by listening to players like you or collecting a lot of data from the players.
What do you mean with not a lot of audio? We've got excellent sound effects from timbre audio, and of course the beautiful soundtrack.
Anyway, thanks for playing! All this feedback is really motivating our team!
