Yes, a quick tap of jump key in the air while having hover jump enabled would still momentarily stop your falling even for a tiny moment, so it costs Mana. Holding down the jump key wouldn't charge you more than the initial Mana until the bar reaches the bottom, so it's better to hold it, instead of simply tapping the key.
With 3 different jump abilities, they all play differently, and have different use cases.
- Multi Jump is good for general mobility, and precision landing, and it lets you move far while in mid air especially when comboed withthe Dash ability.
- Power Jump gives is the most vertical jump, e.g in the vertical room with 4 bouncing mushrooms, you can use it to jump from floor to the top platform without using the mushrooms. The disadvantage of the jump is it takes time to charge up, and stops your movement.
- Hover Jump can be precise, and it lets you skip many obstacles, but it costs more Mana, and I think it is quite slow.
I also have plans on eventually having those abilities unlockable, and upgradable, but that's for when I actually implement Skill Points, and Skill Trees.
Thank you for playing, and all the feedback
