I love this game so much. The art style is adorable and the fact that there's jar rattling sounds when you bump the jar is lovely. It's like I have a jar full of dino toys. It is enrichment!
I also love the bump feature in general. it works well with the fact that your dinos aren't perfectly round, so they don't roll like in suika game. so though you're inspired by it, that bumping feature does help make it more unique. I've sometimes played unlimited bumps just because I want to shake the jar a bunch.
I also feel like sharing that when I was sharing with a friend about the game and mentioning the bumps, i was trying to explain how it worked well and just went "well in the main game they're not a commodity, I mean, they are- wait i think that's the right word, but I just mean- ...dino saurus. (/ :3)"
Only time I had issues with the game was when some larger dinos merging caused them to get stuck together, but it makes sense since they are such funky shapes and the bigger ones can cause more displacement. honestly, it's expected enough that it doesn't take away from the game much for me.
