It's definitely possible to play single player but fair enough. Thanks for checking it out anyway.
The web build has some weird performance issues related to physics. It performs much better with the download build.

ok i went back and dual wielded the download build ... solid little game, great music, cool art espeically the characters. As far as theme my taekaway was its better to eat human trash than natural foliage. The seasons were there but didn't seem to affect anything (type of trash even) but the gameplay is good... I could see a developed version of this being pretty fun as a score chasing party game for two or more players.
Thanks for going back and playing! You're right about seasons not really affecting anything. There is code and design work in place for seasonal events such as sprout outbreaks in spring, heat waves in summer, increased leaf fall in autumn and frost in winter. As is the way with jams, we over-scoped and ran out of time to implement :(
