I like seeing smart stuff, and the way you check the NPC challenge with the mouse indirectly controlled by our character is very smart :D
The explosions are quite impressive, I bet you spend some time working on them!
I would love to see more changes between levels (new obstacles, ennemies, power-ups?).
I also wonder why our character has some stats (HP, MP, level)...? It looks like you used a tool like RPG-Maker but didn't have enough time to fully customize it :D
Still a nice entry! :)
