I like the graphics here. Reminds me of my early spritework. Love the gameplay also. NES feel is there!

Enjoyable game. Well done!

Of course the graphics aren't the most sophisticated in the jam and it's a bit of a bummer without music, but it has solid gameplay and the level design is good. Nice touch to make the stages only scroll horizontally OR vertically, like many NES games of this genre. I would suggest polishing the hit detection a bit more, especially the sine wave ghosts and the big guys in the castle can often hit you even though the visible sprites don't overlap. Otherwise pretty good game.

Would have love some music. It's fun!

I completed all the levels.

The game is fun. It controls well (it feels a bit floaty yet it also means it controls all the better so it's fine), the different enemies all propose their own threat and the difficulty is on point.

Thanks for sharing!

The shadowy enemy that spits red balls is my nemesis.

I liked the character design for the main character, and his jump animation was very fitting for the movement style, if that makes sense. In your next project, I would include music and additional sound effects to improve the game feel.
