Touchscreen gestures have glitches – Zoo Train Review

Excellent idea of the app, however in many parts of the game there are issues with dragging parts of the puzzle into place (pieces do not follow finger movements on the screen or follow half way through and then jump back to original position). Other apps with similar features work fine, so does not look like the problem is in the iPad or the screen. Update with a fix would be much appreciated!
