After playing for 7 hours, I can, for the record, give an honest opinion about this game.
Long story short: The visuals, animations and music are great; just as a reminder should be.
The game mechanics? Terrible:
-Complete lack of depth perception: The front-to-back camera angle in Coin master is how it was in the original. But it seems that the devs took no care in improving it whatsoever. Jumps are almost impossible to judge given this angle. I have the game maxed out at 1280×1024 on android and STILL cannot judge distances based on shadows, etc.
Finally, as mentioned, each of the games have some degree of QoL changes (generally to improving Bonus Stages in some way or another) that makes getting many of the previously ballbusting gems far more reasonable.
So as far as remastering goes they did a 10/10 job, but a remaster is only as good as the games it’s, well, remastering.
