Hi,
Finished the game!
The game mechanics are like in old games from the 1990s-2000s, pleasant memories, especially the scoring and music :).
I think I noticed that when you move on to the next level, there is an option to click several times on the beginning of the level and it seems like there was a jerk at that moment, like it wanted to start twice, it started fine, but visually and soundly it was like a jerk.
I would also like to be able to shoot with the spacebar, the Z and X buttons are good, but they are too close together for frequent use.
The animals were wonderful and it was fun to rescue them, but I would have liked to explore the animal theme a little more. I liked the bunny ear helicopters :).
It was really fun, congratulations!
