-The walking animation was intended to be a little bit of a sassy walk.
-There's no way to lengthen the time text is on screen, but there's a button to skip the text. Tab/L2 by default. If you miss it you can see it on the pause screen with Enter/Start.
-You can skip on the water if you time your jumps with it.
-I feel what you're saying about the boss. I'll try to think of what I can do, but the cat and fairy both have no method of attacking.
-Freezing the game when you lose focus was causing softlocks due to bugs in Unity's core when you return to the game in certain instances, and was pretty much out of my hands. That'll have to be how it is.
-The speed of the cat is a little low since I'll be adding a metroid type speed booster later in the game. The autorun was a suggestion from last DD. I added it as an accessibility option for people who have trouble holding a button down for a long amount of time.
-The reason that you can't collect the coins in the main mission will become fairly apparent. The coins sound strange though? I'll check it out. The coin missions will remove bigger puzzles from the level and just be a straight coin comp for the most part. The coin missions should be pretty finished.
-Her focus is on item use and world interaction. There's nothing in the levels atm that actually uses her, yeah. Was just bonus.
I'm glad you liked the game! I definitely put a lot of focus in some of the smaller details, probably way more than I should. It was fun though!
