Thank you so much, I really appreciate the feedback! There's actually a sword seed to the right of that little tunnel area you can use to defend yourself. Originally, I had planned to place a breakable wall between you and the enemy that could only be destroyed by the sword, but due to issues with the engine, I ran out of time. Same with the water actually, there was originally going to be a well near the bottom area where you could refill your water completely (that's actually why there's only six seeds in the area before that: six seeds for six slots before you could refill it).
I'm really glad you like the concept, though! Right now, I'm actually working on porting it to Godot 4, as I think that would better fit the scope and type of game I want to make (the old engine has tilemap collision issues that make it a HUGE pain to make large worlds). That version should be out probably tomorrow, with some of the features I've mentioned here. Thanks again for your feedback!
