Hey Ale059, thanks so much for the comment and playthrough! 🙏 Really love seeing that.
Nice one on finding all the stickers! 😁 One or two were a little hidden 😅
The MiniGame is pretty tough! You can't really 'win' it but it should be possible (I think) to get an S-tier grade by lasting for 60 seconds or more. I haven't achieved that myself, I think the best I've got is an A grade for 50-55 seconds. I've included the grade times and scores table in the 'Extras' part at the end of the game description above.
Thanks again. 🙏
