Sentry Knight Conquest Very interesting story set even in the first second of the game with the dialogue with the main character and the knight. Beautiful background as well. Interesting, but simple character design and simple gameplay. Reminds me of Knightmare Tower, another amazing game. The final boss is rather difficult, specifically getting it on perfect due to the random black puddles he puts.
EDIT: Replaying it it seems that the final bosses' puddles only summon inside of the red carpet. I haven't beaten them perfectly yet but at least I have a strategy now.
