These are perfectly fine levels. They set out what they seek to accomplish with no unnecessary frills along the way. The eyecandy is little more than it takes to distinguish wall from non-wall, with occasional tile bugs but no great level of detail. The code is slightly buggy (strange number display in the secret level; arrows point toward gems while they’re still being collected in Medivo) but generally works and is sufficient for a set of quick experiments. Level design makes a good effort at not just being straight lines, and there’s a respectable variety in enemy/obstacle choice. The different levels’ objectives are similar enough to make the pack coherent yet different enough to keep things interesting. All in all a successful outing.
