This look like the start of something great, the art is wonderful. It would be nice to have some music and extra SFX to add some more atmosphere to it though.
Sadly, I didn't get very far. My first playthrough I got seeds from clearing the first weed, planted them, then watched as the mouse stole the seeds whilst I fetched water. I then to my surprise murdered the mouse, retrieving the seeds, but then as i went to refill the watering can, somehow lost it and was unable to continue. This is the main problem for me, the controls feel like they are back to front, using an item feels like the primary action, so in my mind should be mapped to left click being the primary button, with dropping the item being a secondary action, that should be mapped to the right click. I was constantly fighting my own muscle memory.
My second playthrough was also cut short as the mouse once again meet its demise swiftly, but seemed to spawn what looked like a packet of seeds, unfortunately it was located outside of the fence to the left of the level, and I couldn't reach it.
Nice idea though, and some great potential. Good work
