Well, my excuse is that this was a rating for the 2021 Minetest Game Jam, and I wanted to rate the games for the game jam specifically. So this was kind of a special case. It feels weird that you can't give thumbs down for broken games for the game jam.
Anyway, I have decided to try it again, but this time managed to make this game work somehow. I don't know how. Here is my new rating: Thumbs down.
Okay, so the game looks pretty nice, the graphics are really cute. I really like the minimalist landscape and how you used sky color to your advantage. Using the few tools that gives Minetest in such a creative way is something I really appreciate! :)
Unfortunately, the gameplay isn't really stable or reliable. The game runs a bit too slow. The idea is great, flying through the world and collecting coins. But performance is poor. The balloon often doesn't react too fast enough to move left or right. And many of the bonuses are placed in a way that you always just miss them. Not sure if intentional.
But the worst problem is this: If your ballon flies very fast, you constantly bump into unloaded terrain, making the game very errating (sadly) and unfun. The performance problem is so bad that it ruins the fun, sadly. :-(
Apart from that, the game would have actually be nice. The game is pretty complete, it's just too laggy. If the game would not be so laggy, I would have given it a thumbs up. But it also gets boring pretty fast. :-(
This might be a limitation of Minetest (because the balloon moves VERY fast at one point), but is still unfortunate. But on the other hand, maybe some trick like preloading the whole level would have done the trick, not sure.
