I really like the style and the fast pace of the game, it’s actually really fun to play.
I do have a few ideas though. It could be interesting to see more maps and parkour-style areas. Maybe some parts of the parkour could extend the timer or give other useful bonuses, so while doing the parkour we are also collecting leaves at the same time.
If you ever plan to expand the project, maybe different maps could have different objectives instead of only leaves. For example, collecting specific items for different characters. Like helping an old man during rainy weather by collecting umbrellas or something similar. Just an idea :)
Also I feel like the zoom mushroom disadvantage might be a bit too strong. It zooms the camera and it also feels like it slows the player down. On top of that, you can’t interact with anything while it’s active (can’t collect leaves or deliver them to Andre), which can cause you to lose the run.
Maybe there could be an antidote item for it, or some of the disadvantages could be reduced.
Other than that, the game is great and I really enjoyed it.
