Hi,
wow, the gameplay changed my prejudice about the cover art a lot! Those monsters are awesome and their animations feel very good, even though I don't think they're drawn by hand (which is impossible in the span of 10 days ':)) The level changing when you go around it felt very smooth, I didn't notice when the new level appeared, so good job! The ambient music is simple, but combined with the sound effects it adds up to a pretty pleasure experience!
Keep up the good work!
