Thanks! I use Linux as my daily driver and workstation so it was first and foremost on my mind. <3
The difficulty is the regular thing I hear about that too, and I understand. I didn't have time to add quite all the features I wanted including defence mechanics or less aggressive varieties of enemies or tune things, so it became hyperaggressive to an extent even arcades wouldn't do. Additionally, I agree the lack of instruction on pollen collection does need to be addressed (it's collected from flowers that bloom after destroying corrupted ones for the record), so I will update the instructions with a blurb on that and plan for an attract mode that explains the mechanics as I add the remaining features in.
Thank you for giving it an earnest shot <3
