I would really like to recommend Beatbuddy, but I just can't... at least, not fully. While it's got a lot going for it, I just can't get past how buggy it is. Although I did manage to complete it, it wasn't without some serious issues. Several times I got stuck in various ways that prevented further progress - sometimes it was a matter of a game event not triggering properly, and sometimes it was due to going some way the game wasn't expecting me to (apparently). I also encountered issues where the controls would just stop working for no reason. Restoring to the last checkpoint sometimes fixes the issue, but this is rarely the case. Most times, there is no choice but to start the level (or entire chapter) from scratch. Do you know how annoying it is to have 30-40 minutes of progress wiped out, have to start over again, and hope you don’t make the same game-breaking mistake again (whatever it was)? Let me tell you - it's really f%@*&g annoying. I ended up having to do that multiple times. And would you believe, as a final bug-ridden cherry on top, the very end of the game also glitched out on me as well? Well, believe it. So on top of all the other frustration I experienced just getting through the game, I didn’t even get to see the full conclusion of the story.
Now, putting all of that aside, what’s actually good about Beatbuddy? Quite a bit, actually. The hand-drawn layered 2D graphics look great, the controls are responsive, the puzzles are generally well-designed, and the music is decent. And that’s a good thing, because the music plays a large part in the gameplay - the environment works in time with the beat of the music, requiring specific timing to pass obstacles or solve puzzles. The first couple of hours are great, as the basic mechanics are introduced. Unfortunately, it starts to lose its luster a little bit after that, as most of the subsequent puzzles are pretty much variations on things you’ve already done several times. So you might start to get tired of it after a while (or maybe I was just burned out from having to replay several areas). I would estimate the overall playtime to be somewhere around 4-6 hours.
Overall, the game is not bad, and I enjoyed it while it was working properly. The frustration from all of the technical issues I had just ended up being too much for me to give it a full recommendation. If you enjoy action/puzzle sidescrollers, music-themed games, and/or games with pretty 2D artwork, it’s definitely worth a look. Just be aware of the potential issues. I suppose it could very well be possible that you'd encounter no glitches at all… but I doubt it (several posts in the Steam forums seem to corroborate my experience). At the very least, don’t buy it at full price unless the developers hire more QA people and/or release a patch that fixes the game-breaking issues.
