I really appreciated playing this game! However, I have some feedbacks to share:
Visual: I think the light is not really useful, and it feels a little bit janky. Also, you should keep the same scale for all your sprites, for consistency. During my playthrough, I found the parallax background a bit distracting. But, I love the way the flowers are generated (procedurally, I guess?)
Audio: Perfect. It suits really well with the stressful gameplay. The SFXs are really good to.
Accessibility: I think the gameplay is a bit flat, because all you do is walking back and forth and occasionally pressing on E. The threats are not really threatful, and we can't really dodge the bird's attack. When I was playing, I found out that the flowers can stack under the same pipe, which makes it difficult to select one. I found the upgrades menu a bit hard to access, and I took time to understand that the turtle was saying tips. I think you should add an icon or a text to the presses to distinguish them. I don't really understand how we are supposed to tell if a flower is mutated or not, aside from the turtle. Jumping is useless, I think (or I did not play enough).
