It would be more fun with a random level generator. 18 is a good start, but more would be fun. (And maybe a bit more challenging, too. It finally started to get good around level 15 or so)
I'll have to play through it again sometime (without so many restarts) but it wasn't as addicting as the warcraft game or others. A fun play none the less second the need for some sort of random generator or at least more levels.
It's always nice when there's games you can actually get finished That, besides relatively short levels, makes it not frustrating.
i felt quite accomplished after defeating this game - it was cool how you could see certain things as the game progessed.
