Concept: funny coincidence, our first idea was also about necromancy of a beloved pet just with point and click gameplay. Nice to see that someone actually made it!
Gameplay: it's some good old fashioned platforming, nothing groundbreaking but it works. The levels are a bit too samey but there is just enough to be engaging yet not get boring. On many levels it was hard to tell what can be stood on and what not, the platforms blended in with the background too mush at places. More contrast between the background and foreground objects could I think solve this pretty well. The rat bossfight was great it had a simple premise, but turned out really fun with the clever level design combined with the available moveset.
Art: Chloe seems to have been working overtime this year with all the unique background arts, they look amazing. Not sure if I've gave this feedback before, but I think the inconsistent line sizing makes some sprites look out of place. This is especially prevalent on the first level. This kind of hurts the coherency of the game's look despite the great spritework. The vfx around the levels and on of the cat are really good, like them a lot. The bloom is sometimes a bit too much though, there were places where it was hard to make out where the cat was.
Audio: pretty good, fitting all round. I liked how each level had its own soundscape, the game didn't feel silent at any point despite the lack of background music.
Very nice submission overall, your games are getting better and better each year! Thanks for hosting the jam!
