Hi there and thanks for reaching out! Happy to help with anything.
I'm not sure which animations you're referring to that isn't being implemented correctly to the other assets - but based on your description it may be the NPC spritesheets? If so, the configuration for all NPC-related spritresheets (Pre-made NPC spritesheets, clothing spritesheets, body spritesheets, etc) all use a 32x32px frame. I think the issue you're facing now is that the character sprite is smaller than all the other assets - so what you need to do now is to increase the sprite size by x2.
The intended size of the character sprites are 16x16, but in order to add customizable features to the characters I increased it to 32x32 and is the reason why the characters would appear small in the editor - it's a small trade off and requires a little bit of adjustment . Hope this helps and let me know if you're referring to a different issue! I'll work on adding a readme to the respective folders to help future devs ๐
Also, very cool to hear you're making games for your kids! That'd be a great core memory for them when you finish making it :) The idea with this asset pack was to always make it easily expandable so I can always come back to it when I've got fresh ideas! I definitely have intentions of making a Space-themed Expansion but it's fairly far in the plans. I can see making a small package update though to help you out ๐ค Maybe introduce it as an Expansion where some guy jury-rigged a small spaceship in his backyard and actually managed to reach space ๐
