I would say nice concept but few flaws here and there.
My feedback:
- Font a bit sloppy, needs a bit of polish
- Auto-watering seems a bit weak but might be intentional
- Not much content to progress to, this would be a good demo i would say tho
- Capped upgrades/no other upgrades results in relying on the 3x boost event to progress. Without it, the gains for last 2 plants are too slow without any oportunity to buy anything to make it faster so maybe spread out the 10 upgrades into more but less gain by each individual level.
Otherwise i would say good start for you.
GL in future.
