For being made in 1988 the game plays amazingly, its kinda similar to castlevania with subweapons but the pace is way faster and flying through the stages is fun as hell
but man this game is pure evil, not only is the final world full of infinitely respawning and BS enemies, the game sends you back to the start of the world if you die to the bosses even if you have lives and to top it all off the 2nd time you fight a boss it doesn't fill your health up so you have to play perfectly just to get to the boss with the same amount of hp you had the first attempt crazy game but i still loved it
