Great art and UI visuals! This is also the type of game with good replayability especially with different strategies you could use.
I must say though, it'd be nice when the game starts, there'll be a prep phase so the player will be able to settle down and process things and its surroundings and there'll be a button or something to start the growth and enemy phase (maybe it's just me, cuz i was surprised when the green light suddenly happened and enemies appear when i wasn't prepared with the whole plants yet hahahah). It took me time to get used to the attacking too so the prep phase would really help or something. Overall, amazing work!
