Screw Pin - Jam Puzzle 4+

This game doesn’t have any flaws. If there is one thing that confuses me, it would be the following: when you complete a level, you can choose to multiply the amount of money you get by watching an ad, but one of the “1.5x” indicators uses a period, while the other uses a comma. I guess I can understand this if it’s so that people from anywhere can understand it, but if it was just a typo, please fix this. I don’t want to give it only 4 stars and I can’t give it 4.5 so I won’t let this impact my rating.
Edit: I later found out that BOTH “2.5x” options use a comma, meaning this is definitely a typo. PLEASE fix this, most English speaking countries use a period anyway. Just for that, I’m removing a star off of this review.

Levels that are unbeatable without special items are sprinkled throughout. It really takes the joy out of trying to be clever when you feel like the game is rigged against you, and you're never really sure which levels you're working too long on. Lv 314 for example has only one strategy through the first 3 screw-boxes, and you can't solve it without at least one hammer. It's pretty blatant with that one. Maybe they'll fix it and the others. As it stands, these levels seem to exist to wear down your booster supply, and make you spend money or watch more ads to generate money for the app that way. I already paid you guys for ad-free. The game's not worth more than that, but you can sure bleed a whale if that whale has an addictive personality. It's okay. I know, they have no conscience. Secondly, this app engages in the common but still gross mechanic of not actually prompting you to submit your rating to the app store unless you promise to rate it 5 stars. They really tell you who they are when they do that. I left a star on because the gameplay itself has excellent mechanics, awarding ingenuity and fast fingers if you can sneak a screw for the next box in the last hole quickly enough. A lot of screw jam games don't have that feature. In conclusion: it would be a great game if you couldn't feel the sliminess all over it.

I picked up this app after playing a delightful little game in an ad (in another game app). It's not unreasonable to expect an ad to represent a game accurately. When I looked up videos of gameplay and found this app in the store, I could see that it was different than what had been advertised to me, but gameplay seemed similar and I could see that some of the levels became intriguingly difficult, so I gave it a try.
Unfortunately, even after quite a few easy levels, the challenge has barely increased. I don't really want to grind through any more levels in the hope of reaching an enjoyable challenge, like the ad had teased. The game is linear, with no "challenge mode" or any other option than plodding through each numbered level in order.
The game itself is decent, my gripe is centered around it not being advertised properly and therefore not meeting expectations.
(One other small note, this game requires internet or data to use. Personally, I prefer games that don't require this because most times I play games are when I catch a few minutes out and about or on the go and access can be variable.)
