imagine you have already worked on the game for 3 days and you have a lore,gameplay mechanic, originality, art and a working game but 4 hours before the jam finishes your computer take 5 minutes just to load one simple scene which makes changes virtually impossible, well that is what happened to me and now i cant finish the game now you might think that is because of unoptimized code now that is true to a certain extent but my laptop has 4gb ram and integrated graphics which makes it really bad but hey atleast i learned alot, so goodluck to you guys!
