Hi, I tried your game and nice work! Really well done, you've got a great level of polish on it. It's really cool how the ball makes different sound tones when it hits based on the velocity, which creates a sort of musical feel. The control scheme also works really really well and is very unique; awesome job on that. I've never played another platformer game like it. I'm only a few levels in at this point but haven't run into any bugs which is great, and I'll let you know if I do as I play further. My only criticism, and it's a minor one, is that the red loading text doesn't really fit with the overall style of the UI. It would be nice if that text was the same blue font as everything else. It would also be cool if you could include Google Play Service leaderboards and achievements. A timer for each level and then a leaderboard for best times would be one way to do it... and it could add a competitive aspect to the game without making it any more difficult for people who just want to experience it at their own pace. Doing that might also help you get more downloads, since it would encourage people to compete with their friends. It's really nice to see that you're getting a decent number of downloads anyway, because this is a high quality project and deserves the publicity.
Any chance you'd be able to answer a few questions about your project? I've been making games with Unity for ~2 years, under the name Anachronic Designs.You can find my apps if you want by searching for Anachronic Designs in the Google Play store. I'm curious if you are using any assets from the Asset Store in your project, and if so what your experience with them has been. I'm also interested to know if you've done any other marketing/promotions for your game besides posting here, or if your downloads have all been the result of people searching for and finding your game on Google Play?
Gave you a +1 and nice review on Google Play, and did a shout out on my Twitter for you. Hopefully that helps you get some more players. I hope you keep having success with this and other projects! I see from your Google Play description that you're based out of Surrey, B.C. I live and work in Vancouver. If you ever want to meet up and talk games dev I'd be more than willing.
Cheers!
