Nice shorty! I grew up when home computers just got into the homes, so blocky graphics and jumpy movements is not blocker for me ;-) So, first of all, well done for the - I guess - one of your first games! :-)
If you are still motivated to continue _this_ project, I would recommend
- Sound effects: when player and enemies move - think of pac man, sound for reaching candle (ta taaa), etc.
- Music volume slider or toggle for on/off
- A bit more intelligent enemy movement - right now they go (a) randomly and (b) also do _not_ move at all most of the time. Also: when you pass an enemy (ie, are next to it) then there should be some kind of danger involved - eg the enemy gets you with some probability or - even cooler: the enemy registers you and follows you for a short time (that way you must not go past it and end up in a dead end.
- Add interesting elements in the level such as conveyor belts, one-way streets or doors, etc.
