Looks and sounds great! The controls are very cloudy, making it impossible to pogo, and this is incredibly similar to hollow knight mechanically and aesthetically. The wall climb boss was good, but it kept repeating its worst attack.
You guys are very talented, with time and fine tweaking you could make something really good! The problem is that to turn it from extremely similar hollow knight to somewhat similar, this will have to go through a lot of changes. Overall, I can't wait too look at more of the stuff you'll make, and hope somewhere down the line you'll find a great and original concept and make something truly special.
(I just learnt this used to be a fangame, so big changes are probably already an idea.)
