this game has so much speedrun potential!!!
I really had a great time and was gratifying to stick around to keep replaying "world" 1 until I beat it. The switch to world 2 was super cool, and I am definitely interested what else there is in the game if i can ever beat it! "World" 2 has a lot of potential, but i suffered from platform readability a little bit. The timing and usage of the new item was instantly interesting , really really fun to use it, but guessing "is this gonna be a platform or not?" was more frustrating than challenging. It wasn't all of the platforms, some of the colors were very clear and indicated what i needed to know, but there were a few confusing colors and platform types i got tricked by several times. Not sure if the trickery was intended since it doesn't really have any kaizo feel to it other than the first falling platform surprising me!
the NES feel with difficulty, precision inputs, music, sprites, and color were all PERFECT. because the NES aesthetic was so perfect, the black rectangle scale tween during screen transitions bothered me a little bit more than it should. (To critique the game's art, i have to resort to critiquing the screen transitions... xD)
I think my favorite part of the game was learning the timing of the gold enemies. The enemy designs were really well balanced and challenging overall. Definitely reminded me of MANY old NES platformers my cousin and I would replay over and over, but only ever beat 1-2 levels whenever we played it haha
And last but not least... thesoundtrack... Old Mines was such a banger!!!!!!! GG WP!
