One of my favorite games of the year up to this point.
Has that classic 8-bit home computer game vibe with great controls and cool music.
Can be super tough at times, but it is fair real difficulty with a hint of rng thrown in to spice things up. One boss battle especially surprised me with it's design that made me thing "how on earth am I supposed to do this" for the first few tries, but later the solution became quite obvious, if still hard to pull off.
Also really fun game to speedrun, with well thought out built in tools and mechanics.
Highly recommended.
