This puzzle game made me smiling the more I played it, the combinations of seed were so absurd sometimes that I  even need to chuckle or laugh. :) It's a cute game with lovely pixel art, and that's why I simply have to congratulate you on the 10th place in the Ludum Dare 38 - well deserved! <3 I included your game in one of our compilation articles about the jam as well as featured it in the related showcase video. :) Thanks for making the game, looking forward to new stuff from you!

Best wishes,


Finally got the ultimate plant!!! Some of the plants were hard to get, but with enough brainstorming and random clicking, I eventually got there! :D What a great puzzle game!
