Difficulty settings + Reset button

In this update:

• Three difficulty options: easy, normal, and hard. These are accessed by clicking the hammer next to the Next Island button in the research menu

• Reset button - you can now reset your research. If you want to beat the game again on hard difficulty, now you can.

• The reset button is in the settings in the main menu (not in the research menu though).

• Difficulty curve: the game should have a slightly more normal difficulty curve now, where earlier waves/phases are easier and they get harder over time.

• Normal mode is also substantially more difficult now.

• New enemy: dragon, unlocked after the 11th research. Very slow but has very high health.

• New enemy: shaman, unlocked after the 10th research. Very resistant to magic damage.

Those are the more major changes in the update.

I've also updated my unity version, which I'm hoping will improve stability. I was planning on doing endless mode as well in this update but I'd made so many changes already I decided it's better to split it up.

I'm interested to hear your feedback on the difficulty. It's definitely something I want to continue working on.

Future updates:

• Endless mode

• In depth difficulty settings + custom difficulty settings

• QoL: resolution/windowed/fullscreen settings + page to view controls
