You were able to select which seed to plant you just had to open your Inventory and select the seed.
I'm already thinking of how to make it more friendly! Thank you for playing it!
Really like this game! Can't wait to see what you do next with it! As others suggested I'd focus on reworking the UI layout, maybe add a few more tutorials to help the player understand what to do. It took me a second to understand the gameplay but when I did it was very fun and built my resources :D . Also maybe have the enemies paused while you are building and when you come back have them start a few seconds later. Every time I came back to that world they just swarmed me.
Okay, you can take your freakin lazers and just walk to round 3! This is such a rage inducing game but I can't stop playing it! Not sure if you are aware, on level 4 it was taking me so long to complete that the music stopped playing. You know like at a party when they turn the lights on saying hey get out of here already! haha
But really a really good game and looking forward to what you do next with this!!!
