I like the atmosphere of the game. I love the spell system with the randomised spell list. It makes casting spells a bit of a puzzle.  A minimap wouldn't hurt, but it's not necessary.

Honestly, I gave up trying to get back to a door after getting a key (And I don't like giving up), The game is quite fun, but I found some mechanics frustrating.  I played for a good half an hour just trying to get to the key, and the couple times I managed to, I ended up dying right after.  I had to stop, then and there, or risk doing some keyboard tossing. 

It's a excellent effort, for sure.  You have a knack for game making, you put a lot into this game and IT SHOWS! ...but I think some of the map layout and mechanics need a little bit more polish. Keep it up, please!

Notes:

• I saw "Litterfoot" on the screen and my mind saw "Litterbox".   I have no idea why...  XD
• Might want to leave notes on game controls on your main page.  Yes, they are in the game, but it can be surprisingly easy to forget them.
• FINALLY, a game with a PAUSE button!  THANK YOU!
• The only problem with using shift key for casting spells is for windows systems. Multiple hits during a short time causes a separate window to open up, something to do with 'sticky keys'.
• Landing on top of the skull pile creates a delay of several seconds before the game resumes.  Also noticed a similar when starting a game for the first time.
• Spell usage felt frustrating, between a combination of never having the spell I want on hand and having a tough time hitting the targets with some of them (notably the fire spell).  Any chance something could be added to scroll through which spell you would prefer to use, since you can see three of them at any given point?
• Starting with a random spell lineup is interesting, but I found it created frustration with the shear frequency of times I died, since it made some playthroughs more difficult than others.
• Getting to the key is frustrating, since it's easy to get locked into a spot with spells that cannot do anything and slimes that have you boxed in.

Really enjoyed the level design and variety of spells, found myself playing for decent amount since I kept wanting to see how far I could make it even though I kept dying it was very enjoyable to keep running it back :D 

Love the way you used the theme graphic, really great old school gaming with old school difficulty! I tried my best but was only able to get to level 3 in my best run before game over, but I had a great time!

Love the spell interactions and the level designs, especially finding secret passages and hidden areas! Love the attention to detail like the piles of bones that kick up underfoot. 

Love the crunchy chiptunes as well! Great work all around :)

Really good, I like how the spells interact differently with different enemies. Only frustration was the spells firing out at different angles making it hard to hit enemies. It was pretty hard too only just managed to get past the first level. It was really cool how you get used to the big levels and build up your mastery of it by knowing where enemies are.

That was fun, I like the old school gaming vibe!

Fun. I found a secret passage OO

Awesome game! I like how different spells affect the enemies in different ways. I accidentally enlarged a slime on more than one occasion. Thanks for your hard work.
