I think the presentation is nice, overall I think the current gameplay loop in kind of boring, there are many variables but If I just focus on growth it is difficult to lose. I think that if I could have more than 1 cactus and I had to manage their health and try to keep them all alive and happy until the end it would have been a bit more entertaining than just trying to get the highest score at the end, but that's just my opinion. I hope you keep improving the concept :)
