This is easily the best ballistic-movement puzzle I’ve yet played. The puzzles are well-designed and satisfying to solve and the minimal aesthetic, with calming ambient background music, is quite elegant. The game is only 51 MB in size, which is important to those of us without massive amounts of storage. And the ads are neither too intrusive nor too long. This game, and the app that implements it, is really awesome. Bravo!
That said, I have a number of minor improvements to suggest (and the game’s version record gives me hope to see at least some of these implemented):
1) Have the number of undos reset when the level is reset. There are only three undos per level. That’s not just per attempt, that’s total. Once you use three undos for a level, you can never use undo in that level ever again (unless you purchase unlimited undos). I don’t see why the number of undos shouldn’t be reset when you return to the level; the later levels have enough moves that running out in a single play is quite easy, and never having them again later quite frustrating.
2) Have the level select pages scroll when moving from one to the next. As it is, it’s not immediately apparent that sliding from one page to the next has actually done anything until you read the numbers on the levels.
3) Have the choose-package button send you to the last used level page. The game already remembers which level you last were at; this would be a logical extension of that.
4) Add a “select level” button to the options at the bottom of the screen. Having to select package, screen, and level all over again instead of just backing up isn’t as convenient, and there’s easily room for it.
5) Make the bottom-of-screen buttons always visible. There’s no reason not to when the next and previous level buttons are always visible already. Also, **there’s a bug** — in one game I played, the button to show the bottom-of-screen buttons mysteriously disappeared. (I don’t recall what I was doing in the game when that happened; I’ve not been able to replicate this bug since.) You *could* fix the bug, or you could render it irrelevant by making the bottom buttons permanently available.
Like I said, this game is awesome. Adopting the above suggestions would, for me at least, make it even more awesome.
