- To easy. Did last level on brilliant on the first try.
- To linear. After level 2, you're not introduced to anything new, neither new enemy types nor backgrounds..
- Skill tree is lame in that game. After a few skills i just kept asking myself what would be the least useless.
- To short. I completed everything on brilliant in a couple of hours. Gemcraft 0 took me several MONTHS.
- No long-time fun, because there are only two challenges: Complete the game, complete everything on brilliant.
- The EXP/Upgrade-combination is funny, but has a major disadvantage. When you have a few strong tower that can destroy most of the normal waves, it becomes basicly impossible to build more towers to block harder waves.
ZZT2:
The genre is called "Hack'n'slay" because you hack on your mouse thus slaying everything in sight. This kind of games arern't complex.
But you are right with the music.
