I trust it (it does appear to Just Work™), but I wanted to verify anyway before sending them out into the world! Oddly enough I did run into the case issue on another project I put together this week, but it was on Windows. It worked fine when run from inside the editor, but the exported version failed until I fixed the filename cases to be consistent.
The pixel art for this is amazing, both the sprite for Santa but especially the indoor areas look really cool. A lot of great subtlety. I managed to deliver 29 presents!
I think my only complaint is that there isn't a heck of a lot of variation so like... you do about three houses and that's all that the gameplay really evolves, but then the game goes on for 5-10 more minutes. I did want to see it to the end, but it would be nice if there were maybe a few other things to do. Also, while it is cute that Santa Time and Ho Ho Ho are bound to the S and H keys, at least for me that was very uncomfortable to try to keep my hand in that position. I have a feeling the Ho Ho Ho was maybe just a joke feature, and also a way to include voice acting, so maybe that was my fault :P
Overall a very cute game with some good Christmas vibes :3
