Thank you for reading and for the feedback Michael!

I’ve added your comments to my TODO and will look at them when I make an update for the book.

Like you say, perhaps the chapters needs more examples. For now, just note that in the subsequent chapters, I will touch upon different cases when pointers are useful and when they should be avoided. Hopefully as your read on, more and more questions will be answered.

Thanks!! 18 on last one is good :D

Well done! Hard but fun

Thanks a lot for the kind words and for buying the book!

Thank you for the list of issues. I have fixed 2, 3 and 4.

Regarding 1: There is no modern OS that leaks after shutdown. While there are some really old OSes where this could happen, Odin doesn’t support any of those OSes anyways. However, a good reason to do the deallocation at the end is to keep third-party memory analysis programs, such as Valgrind, happy. I have added a note about that in the book (update coming later today or tomorrow).

The updated version (https://zylinski.itch.io/odinbook/devlog/848116/version-12-new-section-on-address-sanitizer-and-lots-of-small-fixes ) has fixed this.

Thank you! It’s great that you inform me about this confusion, because I should really make sure to stress the difference between them. After all, they both contain the word “set”. I’ll add fixing this to my TODO list.

Thank you! Happy that you like it

Thanks 😻

Thank you 💖

Thanks for the kind words!

You are completely correct. Sorry for all the confusion. I interpreted both the VAT help text and the numbers incorrectly. “collect by itch.io” does indeed use exclusive tax.

To anyone reading this: I WAS CONFUSED, PLEASE IGNORE ME.

You can only do “VAT exclusive” if you choose “direct to you” payout method. I use “collect by itch, payout later”. With that option VAT is always included. I can’t use “direct to you” since I then have to do all that book-keeping of every single european who buys my stuff myself. One of the main reasons for using something like Itch is that they can handle these VAT things towards EU. But in that case it’s also important that the correct VAT percentage is deducted.

The price shown is always including VAT. So if I put $20 then everybody pays $20. If there is VAT involved then I get less. People expect prices with VAT included, so that’s good. If it was not included and it said +20% instead of roughly +5% (as it should be for a book), then less people would buy it.

In any case, the problem is that a VAT of 20-25% is used instead of a VAT around 5%. It’s using the VAT % for video games, not the one for books.

I just wanted to say that I’m a writer and I’m affected by this too. I assumed it would use the correct VAT rate when I picked “book” as type. I’m selling a $20 programming book on Itch and currently losing $2-4 on many EU sales.

This brings me joy! Thank you

Thank you 😻

Thank you! It’s warming to hear that you liked it 😺

Trying butter with everything is the sign that this is indeed a true adventure game, although in a 2D sidescroller package

Thanks for being interested in my future projects! :)

Thank you so much! 😻 Happy you enjoyed the cat controls!

Thank you 😻✨

I wanted to come up with a new pun to write here as a special present for you, but I’m afraid I might have punted all of them into the game already

Thank you 😻✨ It warms me that you liked the transitions, I put lots of care into all that stuff

Thank you! I will try to fix it, I take crashes very seriously. I think there might be a random crash affecting Mac and Linux platform somehow. I will investigate.

Thanks for being interested in future projects! :)

Thank you! Happy you enjoyed it 😻

I am sorry about the crash. May I ask what platform you ran on and when you downloaded the game?

Thank you! 😻 I love this review

Hi Kenneth! It is very heartwarming to hear that you liked it. It’s always hard when making something of actually being sure if anyone else will like it. So thank you!

For the color palette I used is this one: https://lospec.com/palette-list/retrocal-8 … Early in the development I realized that the current colors where waaay too dark and also I used too many colors, so it started to get messy. So I found that palette and did a big color-swapping-session. Here’s a before vs after video of how the game looked https://www.youtube.com/watch?v=jDRNVHJBeeU

Good luck on your gamedev with Raylib!
