Hi and thank you very much for this really nice demo ! I would like to address a few things here to justify my stance on your game !
The graphics are stunning ! It reminds me off shovel knight , but a lot more blue , and that repetitiveness can be kind of tiring . Nonetheless , it is very unique !
The music can be nice for the first time listening to it , but since this is a difficult game with a lot of trial-and-error kind of gameplay , it can get exhausting very fast . I get that it is supposed to be ominous , but after a while it becomes monotonous and sometimes tiring to listen at due to it's intensity . I think maybe more easy to listen bgm should be used during the hard platforming stages . Nonetheless , the music is very nostalgic , and i really like that about it !
The gameplay is surely very fluid , making the platforming sessions doable , but the input and frame lag due to the animations (notably crouch , dash and slingshot) create a plasmatic sense of difficulty that is more frustrating that challenging , and that is a shame since the puzzling platforming is masterfully done ! Also as a side note , the paterns for a lot of the moving platforms can take a lot of time , and that is taking the immersion from certain stages (aka. second tower , first sideways moving platform) due to waiting to jump onto them .
Also i noticed that the only way to obtain collectibles is through floating coins (correct me if i'm wrong) making the monsters presence obsolete since they don't seem to have any droptable and only serve as obstacles .
I know this might seem kind of a hard approach on the game , but i really do believe it has incredible potential , but at this point i find it to be barely playable due to the few and sparse issues it has . The fact that this game was developed in a month has me in awe ! Good luck on the competition !
