Hints and Tips

Tips for beginners (Start and early game)

 * Save your gems (The green ones) until you have 500. You can then buy the chronosphere artifact. This will give you a bonus to runestones. This will make it easier to upgrade your artifacts.
 * Don't instantly open your boosted chest(s). Wait until the last few seconds and keep buying upgrades. You can't buy upgrades you can afford, but you can receive them if you can't buy them. This will give you an extra boost to get you through the stages.
 * Any active quest will be completed when you time loop. So make sure you have a quest active when you loop.

Tips for the intermediate (mid game)

 * Keep the Huntress ring equiped. You need her "BIG GAME" and "OPPORTUNITY SHOT" skills to have a chance at collecting dropable artifacts. (Arrowheads, Eyes and Bones)
 * Start your runs with just the first 2 heroes. 2nd one being huntress. This will allow you to get the most permanent levels the fastest. These give you the skillpoints needed to maximize the huntress "BIG GAME" and "OPPORTUNITY SHOT". These will increase the artifact droprate, which will give you a significant boost to DPS and GOLD.
 * Once you have maxed out Bones and Fingers (Both at 1000), think about switching to ranger. She can help you get the other 2 artifacts (Horns and Eyeballs), next to arrowheads, with her "TROPHIES" skill.
