Hi nobusawa, thank you for your review, it's really helpful !
I understand the issues you've encountered and I will work on them as soon as possible. Spelling mistakes will be easy to correct, it's a simple .txt file that anyone can edit, no code update is needed. So this point will be fix as soon as I find those bad spelling. About the tutorial and more informations on what's going on, it's a tricky part for me, there is an incomplete in-game tutorial that I need to finish. If I understand you well, you did not knew what's happening on your planet and what to do, there is no main goal for now, just select planets and wait ( you can extract ores and matters, craft items, upgrade your spaceship... ).
Thank for pointing out those issues and stay tuned for next update that will try to fix those problems.
