After many months I still enjoy to play this! Today I got six gargoyles from the first orb.
I often try to do the challenge to clear everything with 13 hearts remaining. Does somebody have other challenge suggestions?
I've played this almost every day since it came out about a year and a half ago, so relaxing, so adicive, such a good game. These days it's mostly clear screen as fast as possible, but some of the personal chalanges I've done in the past are: finish without collecting the mine king scroll. Never use the crystal ball. Play VERY drunk. Save all slimes.
1. Speedrun the dragon as quickly as possible (helloyyy has done it in a blisteringly fast 1 minute 44 seconds)
2. Speedrun a perfect game/full board clear (i.e. only level up or grab a heart when you completely run out of hearts, so that you get as high a score as possible) (My best time in version 1.0 was 3:20, haven't tried in new version).
3. Beat the game with any of the 4 achievement stamps (click "next page" on the instruction booklet for an achievement breakdown).
4. Beat the game with 3 of the 4 stamps in a single run.
5. High score or speedrun with 3 of the 4 stamps.
6. Beat the all time high score with 3 of the 4 stamps (judging from the comments, it's _319(!!!!)_ points, without ever touching a rat, egg, or the lovers. But apparently 325 would be the all-time high score for the whole community).
