Here is my opinions:
1) Game is awesome, tho short atm.
2) Flowers are ANNOYING! Too much petals, seeds are too infestive, spreading like crazy.
3) Red Sand is limited. Sad...
4) Sand is limited. Kinda MEH, because flowers gives more money then you need. Those pesky petals tho...
5) Water, sand, Red sand automation require!
Overall, so far a game for couple very invested hours. 5/5
