"WOW" I beat all the levels, not without dying a lot in the process. Super cool to have a boss fight at the end, especially against this very cool looking and animated shark, funny that it is probably one of the easiest levels but that doesn't matter much.
This is another one which 100% feels like a NES game, which is why we're here, with just heavy and slow enough control for the game to still keep being super fun, and the exact visuals, sounds and music, gameplay loop which feels both familiar and unique and the kind of level and variation between levels you would find there. Infinite continue was the appropriate compromise in my opinion so that we get to see all the content during the jam while each level can be kept hard enough. There's one level where I died several times, I think it's the seventh one and judging by the screenshot I think it was indeed this one.
I greatly enjoyed my time with this game.
