Absolutely wonderful. The game is beautiful, I adore the handdrawn style - the houses and the environments look phenomenal, with tons of character.
Gameplay is really fun, managing to be challenging without becoming frustrating. The randomness of the lightning strikes worked really well - you could plan ahead and mitigate the impact of potential strikes, but you have to accept some level of damage is inevitable and adapt when it happens. The number of houses required for each stage felt very nicely tuned to force risky decisions.
I'd personally love it if the various tools were toggled on/off rather than single use only, but I really can't fault anything else - it's just fantastic!
