Solid Jam entry.
Pros:
I did like the tetris inventory and had fun goofing around.
Cons:
Tile size is a bit small so it feels like you are making baby steps so the movement does not feel great.
The perspective is a bit odd and somewhat skewed.
I did not like the 45° "free look" all that much.
Combat could need some more feedback (but so does mine).
What really annoyed me was that you use "R" to restart the level causing me to go some unintended restarts.
Overall a nice entry. Keep up the good work.
