This is super cute!! The game itself is adorable and sweet, the writing is INCREDIBLE i love it so much ; u ;
but i have. a pretty major complaint. about the accuracy? like i realize this is very simplified and cutesy but. you wouldnt, say, put a hairless dog in a game because its a stylized version of a fluffy dog. plus, games and media influence the public's view of dinosaurs and other prehistoric creatures in a very big way! so, a few things ive noticed:
-stilts is a pteranodon, not a pterodactyl! pterodactyls didnt have those iconic crests! plus, they were covered in fur-like pycnofibres, like a fluffy coat of fur. also, the tips of his wings should be rounded, not at a sharp point! rounding them out would help both accuracy and cuteness! :D
-spike's legs should be about the same length as her arms! spinosaurs had fairly short legs, as weve discovered in recent years! the sail is also the wrong shape, but that can be excused because of cuteness and simplicity. her hand also look to be poitning downwards, but again, simplicity. (luckily for spike, unlike most theropods, we dont actually have any evidence of them having feathers, so her without floof is perfectly plausible!)
-i don't really know whats going on with the bumps on persephone's back? that might just be stylization tho
-pretty minor, but duke should probably have a row of spines along his back iirc? i may be wrong on that one though.
