Hi, thank you for trying the game and giving this much time to give me a well made feedback on my questions!
Yes, I was feeling the jumping physics is a bit odd, that is why I asked to confirm myself, thank you for letting me know! By the way, I have made so the ball doesn't fall at the same speed in the water by reducing its gravity so it would feel like floating, but still it would sink if you won't jump, but yeah I will modify it so it falls less rapidly to keep it more natural!
Yeah, I will most probably add more soundtracks to make the music feel less repetetive!
Regarding puzzles and parkour, I want to keep a balanced approach on both things! (I didn't realize I made something that could give someone "Getting Over It" PTSD lol) But yeah, I am aware the puzzles need to be better, I will hopefully be adding better puzzles in further levels!
And regarding the spikes, yes I will fix it next update for sure!
Regarding the bug, there's a bug where if you are in water with another ball and quickly switch it to a different one, it would still take damage (and same for lava and spike), maybe you switched when you already entered the water? I will try to fix this bug next time too!
Anyway thanks again for all the feedbacks! =)
