I hate bees even more than I already did, thanks ;)
First off, excellent twist. A day/night cycle is something I tossed around doing for my entry, but I'm glad I didn't because you pulled it off much better than I would've. The snails in particular were inspired. I also think the Mario-Kart-style power ups work very well in this style of games.
The visuals were perfect and felt well-polished. I like that each level has its own theme.
The music worked for me, but the movement sound didn't. I ended up muting the SFX (thanks for letting me do that!)
My two (somewhat minor) complaints are 1) the movement isn't locked to a grid and 2) the difficulty within the levels.
For the movement: The way the movement is implemented led me to getting caught on corners occasionally which is frustrating. For a "pac-man-like", I expect a bit more forgiveness in the timing of turning corners. The speed and responsiveness felt good, though.
For the difficulty: The game overall has a pretty good difficulty curve. The last few levels felt appropriately frustrating. But I kind of wish the levels themselves started easier and ramped up (like by starting with fewer enemies and spawning them in over time). Instead, we stay at the same difficulty the whole time. Moving the flowers around is cool, and I liked it at first, but after awhile I felt like most of the levels overstayed their welcome. I would have preferred shorter levels, or, ideally, for the levels to change more over time.
These things didn't stop me from enjoying the game, though.
Next is more of "unfulfilled potential" than a complaint: I wish that there was a bigger difference between the day/night behavior of the enemies. My favorites were the snails, because they behave totally differently at night. But I think you could push it further. What if during the day, you could pass through the snails, and they only blocked you at night? What if, too, they also blocked other bugs? A thought I had, was that the "day reset" powerup felt just a little useless. But if the snail worked this way, you could make the day reset a "cycle swap" powerup that swaps to day or night instantly. Then, you have a situation where you could pass through a snail, then use the powerup to immediately block off a bee chasing you. Just a thought I had while playing.
Sorry if my feedback is too rambly. I enjoyed your entry, and I hope some of this is helpful for the future!
