The only reason I'm not giving this a total 5/5 is...enemy progression. It seems problematic to have every single enemy in the game shown by what is essentially level 2. Still, it's fun, well designed, addicting, and fleshed out with music incredible enough to make up for the level progression, so you get one anyway.
Tips for the Whiffy challenge:
1. Don't bother at all until you have full upgrades.
2. The most important thing in this challenge is speed control. Don't go to fast and try to stop in between two passenger groups at a time.
3. If you crash or get a delay of a second or more on any hill but the one with more than 2 passenger groups, restart as you can't win after that.
4. Don't expect to do any better than 5th.
Wow @ the music, just so relaxing. Gameplay ok, could be expanded a fair bit. 4/5. On another note, a few ideas to help make a multiplayer (if you do, and I think you'd do well with it): 1. Multiple types of each class. For example, you could use a normal wizard for the witch slot, which would do what warrior does now. 2. custom deck builder. 3. drawing seems very, very underpowered in this game.
