Hii! Thank you so much for playing, but especially for your well thought out feedback! We truly appreciate the time you have put in writing the feedback.
The game should work with arrows as well, but I think we forgot to mention that! I agree with you about the intro and to be honest, we have learned so much from other contributions in the jam - one of them being the stretching out the dialogues/giving control to user having a "Continue" button etc.. Also thanks a lot for the feedback on the instructions like "click on the upgrades". Sometimes we get too excited and forget to put in the basics and it is a blessing to have a community like the one here on Itch tell us about these misses.
