There was definitely a "sweet" spot once you get about 4 flowers going where it felt really fun! It's pretty difficult to get it started, having to maintain one flower for about a minute and a half. Maintaining more than 5 flowers at a time without any hotkeys was also difficult since it may not register input and de-select if an action is still occurring or if you miss click as well. If it's possible to maintain that difficulty when you have 4 flowers for the entire gameplay, that would be the perfect scenario but otherwise good job!
For a first game jam on your own this is very impressive! Keep practicing and getting better you'll get better everyday!
