The only flaw is that sometimes the controls aren't the most responsive, but I'm playing a game about an evil calculator, and the controls aren't so unresponsive that they hinder the experience - i.e., it's very easy to excuse. It's absolutely worth the premium upgrade if ya dig math puzzles.","version":"3.0.1","date":"2023-02-18T00:00:00Z","rating":5,"app_id":"com.cinqmarsmedia.devilscalc","username":"Emilio Moreno","title":"","country":"US","tags":[],"review_id":"fdea3a7e-811e-4441-a11c-63c50a9a3e32"},{"content":"Fun puzzle game all about numerals. I enjoy the non-algebraic puzzles, always a fun realization. The built-in normal calculator isn't great, it fails to register button inputs a lot, and it doesn't let you chain calculations together like you would expect. Also, the note taking screen doesn't let you set your cursor, so it's much better to have a pen and paper on hand when you play.","version":"0.5.5","date":"2020-09-21T00:00:00Z","rating":4,"app_id":"com.cinqmarsmedia.devilscalc","username":"Alexander Owen","title":"","country":"US","tags":[],"review_id":"2960af4a-aece-4ecc-8a08-1d9b7282a87c"},{"content":"the game is fun so far, although a bit wonky/unresponsive here and there. i am wondering how i get the free upgrade?(im a student) and if the game is also free for students on steam.  edit: it was really easy to get the key with my student email, so nevermind! I will say this though, i wish the game ran a bit better on mobile, as that'd be my preferred way to play. It's not that bad really, just a bit slow. Eg when I tap buttons, they aren't immediately reactive. Other than that, great game.","version":"0.4.0","date":"2019-07-13T00:00:00Z","rating":4,"app_id":"com.cinqmarsmedia.devilscalc","username":"A Google
