Overall a very addictive and hardcore game!
As for feedback, Id say :-
- Firstly, I'd suggest moving the player, water can, plants and everything else thats above the GUI, to be behind the GUI.
- Secondly, I'd suggest making the game over less sudden. The game ended pretty much immediately and I needed some time to figure out what happened. So, I'd suggest something like a death animation or something.
- Thirdly, I'd suggest lowering the speed at which the orders come, I believe it was way too fast.
- Lastly, I'd suggest reloading the scene instead of just showing the game over screen and start button.
And, for the stuff I like :-
- Firstly, the music is amazing!
- Secondly, the idea of growth is well executed! 5/5!
- Lastly, the game is quite addicting. Good job!
