I've reached out to the developers to ask if they could provide a publicly available link to the ROM. Unfortunately, their agreement with McDonald's prevents them from doing so at this time.

We also cannot share information on how to download it as it is against Rule #2 here: https://docs.retroachievements.org/Users-Code-of-Conduct/#rules

Thanks
Undevil 24 Jun 2023 05:20
the website version is on v1.6 can you support it too?
Sutarion 24 Jun 2023 15:37
Support has been tested and added for v1.6

Thanks for the great set. Just a heads up though, there is a typo with "remaining" in the player activity
Sutarion 29 Jun 2023 02:43
Thanks for the heads up! It has been corrected.

Great game but I got a really weird glitch; after I picked up the first grimace shake in game my Gameboy started leaking purple ooze and started smoking. Other than that the skateboarding is pretty fun

Had a great time at Grimace's birthday party! Presents, Milkshakes, and McNuggets for everyone. Thanks for the set Sutarion.
Aros2k 19 Jul 2023 15:30
Very nice set and a fun game too! The score attack I don't get though, getting all presents still leaves you miles away from 150k can anyone help?
Etron 19 Jul 2023 21:53
@Arok2k you get 2x points in hard mode and you can get extra points by constantly grinding and kick flipping.
Searo 29 Jul 2023 21:41
Very fun game and set, thanks Sutarion :)

Platinado/Mastered, fun set and game with surprisingly cool music!

This game is now freely available on itch.io. See the forum post for a link!

When going for the 100% level times in hard mode, there's two important things to note. 1. You can't skip any of the levels, as it will lock you out. 2. Restarting the level won't reset the timer for the level. (I.e. you mess up 40 seconds into a level and restart, you still have 40 seconds on the level timer)
