Great Game, just fix the ads.

This is an amazing game, it’s fun, has good graphics (for the time, this was made in 1989), and deserves better treatment. You can play the game offline, but you are limited to not being able to rewind and save. The problem is the ads (as all mobile games are), however. You can’t even save without viewing an ad! Not only that, but the game gives you an ad often when you pause! Sega, remove these issues, and I will bump this up to 5 stars.

Great Game, with one exception

Great Game, I really only have one minor gripe is that you have to pay to be able to play it without ads. You have to pay $2.00 USD in order to be able to play the game and not have intrusive ads ruining your fun. If whoever does the Sega Forever line of classics can stop this two dollar B.S. just for a quick $2.00 from someone paying to get it without ads? Really? If your going to make someone pay for the full game without ads anyway why don’t you just have them pay $2.00 to even play the game I’ll continue to play the game once but, until there’s an update where we can play the game without ads and not be out $2.00 for this scummy business model. I don’t mind paying for extra characters in like say a fighting game since that my favorite genre but, come on really $2.00 to play the game with no ads?

Don’t Get This Game! Not Age Appropriate! Good However.

You will notice when you get this game it is 9+ (from the App Store 9+ means cartoon/fantasy violence) but this is more than cartoon violence, this may seem shocking, but there is some mild blood every time you defeat an enemy, the storyline is more than dark for 9 year olds, it’s about rising from a grave to defeat enemies attacking it. This should be age rated AT LEAST 12+ for mild blood. The game is good nevertheless, going back to the 90s to play the nostalgic beat-em-up on a really annoying piece of mechanisms. The shocking age-rating is why the 3-Star rating from me is shown. There’s also some gore! 12-17+ age rating for me. Shocking age rating for sure. Thank you for reading this long piece of writing. SEGA, please change the age rating if you read, I just want kids to be appropriate, please change the age rating, it would make the app much better. Thanks!
