Cool art, and a nice old Zelda-like dungeon game, but I completely missed the time mechanics (I haven't 123 on my keyboard and just smashed through all enemies until I found the cheese).
The character seems very little compared to the environment and the sounds were a bit repetitive (a background track would have helped I guess).
Also, I think I wasn't affected by the spikes, but I like that enemies could be hurt by them.
