Hmm, I'm a bit mixed on this one!
Overall it feels like the game is rather high-quality, particularly in terms of presentation: the interface is clean and intuitive, there are a lot of nice touches like tooltips and transitions that make everything feel stylish, the characters and world are cute and charming, and the gameplay is classic Joust action: simple but fun! There are some rough edges here and there, such as how the characters feel very stiff (no flapping wing animations?) and the game is rather dry in terms of special effects (no sparks for clashes and hits), but overall it is pleasant and appealing.
However, once I got past the surface level presentation and sank my teeth into the game proper, I found myself somewhat unsatisfied. The combat was just a straightforward Joust clone without anything significant added to it beyond the character abilities which are barely noticeable, and I'd say that while it's decent, it wasn't even quite as satisfying or smooth as the classic or derivatives like Balloon Fight. In particular I was really disappointed with the enemies you fight as they all act practically the same and just become tedious and repetitive to fight: with the way it gives them all stylish team names, I was really hoping each enemy team would have a fun gimmick, strengths/weaknesses, or wildly different AI patterns like you'd see in something like Punch-Out.
So yeah, unfortunately it feels like a classic case of style-over-substance. It's competently put-together and not bad per se, so kudos on that, but at the end of the day it just feels like a clone with nothing unique or satisfying to bring to the table, especially with its repetitive and overly-simplistic combat design. For something like this, I was hoping for something more exotic, like Hammerfight, but maybe that's just the quality visuals here really bringing my expectations too high for the gameplay to live up to.
As a minor side-note, my old man hands quickly got tired with all the mashing to flap: would love it if there was an auto-fire, or if maybe the strength of the flap was increased so the amount of presses could be decreased.
