Quick hint: When you're in the top of a watchtower, your range increases. This INCLUDES the quake-leap ability, making you capable of jumping across half the map, over buildings and everything. You're welcome.
The 3-min-slaughter missions bug out after you've completed them once, and remembers how much time that was remaining and puts it as the time you get every following round.
This game has clearly not been thought through. Per example, the last boss' spells all seem random: Including minion spawn. I might be wrong about this, but if it's true, it needs fixin', ASAP.
The same boss also has a spell with magic circles: They pop up and damage right away, making it almost impossible to dodge them with nothing but luck. On top of that, multiple circles can spawn in the same place, knocking off 50+% of your life.
Right, a quick sum-up of the issues in this game:
The controls aren't responsive enough in combos.
The voice input is just a terrible idea, especially when two voice inputs are triggered at once.
If the game works slow-ish now, then I don't want to imagine how it was four years ago.
Aim for difficulty rather than fun.
All in all, a bad game. 1/5
