1:03:33LaresYamoir Hi Casey. I'm currently working on an OpenGL framework for games. Wanted to ask whether I can use the code up to Day 023 (Live Code Editing), with the intend of making a commercial game eventually with it. Might be important to note that I'm also streaming, so the code might be visible sometimes when I stream framework development

1:03:58gimpycpu I know you said you really like discriminated unions, but how do you deal with managing the big case switch they may cause? That is usually handled by the OOP model by delegating to the object

1:09:34elxenoaizd A lot of the times when you develop something, you write it in the simplest way that just works, then you polish it to something good and more finished (e.g. what you did with dsound). For someone catching up, do you think it's good enough to just study and focus on that better version, or is there a value in writing that initial version ourselves?

1:10:47SnowyCrystalz Hey Casey! I just found your series and was amazed that you are creating an entire game without using an external library like SDL (from what your episode one said, at least). I really wanted to watch your progress through the series but I have no Idea where to start in the 200+ episodes since I already am working on an SDL OpenGL game. What is your suggestion?

1:14:24NoRaD91 How do / would you deal with collisions between multiple entities in terms of collision resolution, not detection, like deciding how to resolve conflicts between multiple moving things? I kinda hit a wall there not seeing solutions that aren't very ugly (especially movement-order dependency)
