If you like to watch ads, this game is perfect for you as 90% of this game is just about watching them. Gameplay is as bad/boring/unintuitive as most of the games in the exact style. Ad removal is discounted from 132$ to 19$ which the later iw not only vastly overpriced, but this sales tactic as a whole is completely illegal over here in the EU. Wondering why the appstore just allows it

Pretty fun so far! I really like unlocking the new stuff. Dev: (This may exist at a point I haven't made it to yet, but...) I'd really enjoy being able to change enemy shapes, backgrounds, colors, add color trails to enemies... Basically just more customization, to keep the visual exciting. =] I have some ideas for attacks, enemies, and special powers, as well, but I'll wait until ive seen more of the game to mention them. They may already be in-game beyond my top level, lol.

There are too many unnecessary buy options, in my opinion. I've had my share of experience playing a ton of these games. The ones I see doing the best are the ones with bundles that actually help the player a good amount. As compared to here, it feels like I'm paying five, ten, or fifteen dollars for an upgrade, so minor, like increasing the game speed to 2x for $2.99, then offering a 4x upgrade right after for $4.99. Just seems a little excessive other than that the game is extremely fun!
