Hello,
This was just a great entry, really.
You have created excellent short puzzles with the levers and the flight ability, I have liked them very much. They are well placed and well designed: they force the player to think, to use one ability, and later on to use two abilities to solve them. Great puzzle progression.
The level design wants you to keep moving forward and explore.
And freezing the water is a really n-ice mechanic. You should explore it more and make a game fully centered around that concept!
Jump physics could be reworked to feel more natural.
Also, when playing Metroidvanias with shooting mechanics (long range attack), usually I prefer to be able to keep running while shooting. But I understand this design decision.
Congratulations!
PD: don't hesitate to try our game :D
