Most Flappy Bird parodies seem to not change much, but this one works really well because the core is completely changed. It would have been easy to stop at "Flappy Bird but you can move the pipes" (which is already a solid core for a game), but this game has a different design completely. Having a draggable object for the score as opposed to every time a tree passes is a great idea and adds a dilemma for the players to decide how to solve: Is it worth it to spend my time for this extra score or is the risk not worth it? The voice lines also add a lot and wanting to hear them all adds another incentive to keep playing. I couldn't quite make out what some of the shorter ones were saying, though. The graphics were all nice and fit well- I really liked the small things like the particle effects on the leaves of the tree.
There are a few issues I had with this game, though. If you drag the tree up from too close to the top, your cursor won't move off screen and the tree will stop abruptly. After figuring out that dragging it from the middle eliminated this problem, I went with that instead, but I think it's something to take note of since it may be frustrating to new players. I also felt that the wasp's hitboxes were really hard to hit because of their movement. An idea for a way to improve this is to be generous with the hitboxes. For example, meaning that you may not click exactly where the wasp is but it still counts as a kill because it was close enough. Same for the player hitbox. If its hitbox was a little bit smaller, then they could still survive if they barely scrape the tree. I don't want to be too obnoxious- it's your game after all- but just throwing some ideas out there as I feel that games that are skewed a little bit in the player's favor make for experiences that the player often comes out of feeling better at.
Anyways, if you disagree with me that's totally ok! You know best when it comes to your own game. You have a really solid game overall and I really enjoyed my time with it. Good job and good luck with the jam results. :)
