Well, you can definetly tell someone with experience has made this, the game feels extremely juicy, super clean and consistent graphics, really matches what i see when i go to a bar and there's an old dude gambling with all the animations and sounds, the text pops up perfectly, nothing just happens and every single detail has an animation, it truly couldn't be better visually.
The audio also adds to how good it feels, the spinning, the super spin sfx, the points being calculated, the same way everything has an animation everything has a sound effect and it adds so much to the game, the only thing i don't like audio wise is the background music, i find it kinda annoying to be honest.
As for the theme, it is a bit generic, and it's a very literal interpretation of "spin to win".
Following the theme, gambling is inherently serious, but i think it's missing just a little bit more to push it over the edge, some other similar games added just a tiny bit of story to emphasize the seriousness of the situation.
As for the gameplay, it is simple and fun, i just find that there is a lack of information, you can deduce what each tile does by just playing, but a hover with information would have been nice. As for the upgrades, they are more inspired than other games while not doing anything revolutionary or game changing (that i've seen), but a very positive point is that they DO make you feel more powerful when you buy them just by reading the text, you can tell they will do something good. Another thing i don't quite like is upgrading being limited to between rounds, that's something i personally dislike, as as soon as you finish buying them you are once again left to rng, and you have no way to adapt to the bad luck you're getting, but i am pretty bad at playing so maybe it's just a skill issue for me. Finally, the super spin feels great and is fun to aim for, but, what does it do? is it just more speed? if so what is the benefit of spinning faster? or does it increase odds of landing on somewhere good? i think that a small short tutorial explaining this core mechanic would have been good!
