Frustrating.
The core gameplay is good, minus some tedious trial and error stuff, and I liked that it went for 'easy to die but plenty of lives available' thing. However, it screwed me right at the end when I got killed by the boss, with over 50 lives remaining, and it wouldn't respawn me. It loses marks for that because that's a gamebreaking glitch, even if it's incredibly rare. Other than that, a fun/funny game.
