THROW THE GOBLIN!!!
The story is definitely the highlight of the game. I really liked the serious and heartwarming direction you went with Yuyuko's backstory - and the final ending also surprised me quite a bit in terms of both the unlock requirements and the ending itself.
The gameplay is pretty whatever with how you can't die, but throwing Suika is pretty funny.
Finally, I like the overall presentation of it. It's true the art has a lot to be improved, but I can tell you put a lot of effort into everything and it's very sweet to see.
Congratulations on your very first released game! May this be the first of many.
