I understand that very well and have great respect for so much programming skill, but in the end I always have to base my overall vote on the finished product that I have at the time of the review during a broadcast. Take your time when looking for and fixing errors and give yourself a few days of rest. As you say, this is a hobby project for a free game and there is absolutely no time pressure, especially since the game is actually already finished. 🙂 Apart from that, even in the boom years of the Amiga there were serious bugs in commercial full-price games that could not be fixed with a patch without starting a costly exchange campaign (e.g. Turrican 1). I am very happy that there are websites and projects like this one where the community can provide active help, not just error tests and suggestions for improvement. Otherwise such great games and our live streams would not be possible in the first place.
Back to the game: Unfortunately nothing has changed with the current update, despite the missing red skeletons. The game crashes again in the first level of the 5th world. 🙁
