Instant fun on pickup and play
I like the simplicity of the gameplay that yet you managed to find some nice twists, like the extra hp granted either from score or that can pop up to collect every once in a while. The music is also really fun with its cartoon like vibe.
My only nitpick would be that with such small sprites it can be hard to read gameplay at times.
Other than that its a fun little arcade like entry.
Good job :)
