Thanks a lot for your comment! I intentionally kept the first entity simple so the player wouldn't get frustrated and quit right at the first level :D The real challenge comes in the final levels, where all the monsters are present and the character has to complete the objectives without dying—because if you die on level 9, you get sent all the way back to the start of the game :D
I created this HTML5 game in a very short time; my goal was to see what I could and couldn't achieve, and to see how different HTML5 is from Windows programming. Thanks to this game, I am now developing a co-op horror game in HTML5!
