Another quick update for today, as I felt the last update still needed some smoothing out. Most noticeably, I've increased the number of obelisks to 5, but to help people find them more easily they now draw "ley lines" toward the other 4 obelisks when activated. This will also help see them if there's a bit of vegetation around it (although I've increased the clearance area around them as well).

Additionally, I've added a new set of elemental upgrades, which increases the damage and duration of elemental effects. There are also now heal and coin upgrades that can be taken for a one-time bonus.

The spawn tables have been revisited, in an attempt to smooth things out more in the early game while providing more of a challenge later on. This may still need some tweaking, as the new ability upgrades can change things significantly. Minions also now have health scaling increasing in the late game, particularly the ones that appear in smaller numbers.

Enjoy, and as always let me know in the comments if you have any suggestions or run into problems!
