Fun game if you are in an early 90s mood! I donated some bucks after finishing the game. Because the dev is working on updates, I have a few more remarks:
- In level 4 I could directly walk outside the level back through the front door (v1.1);
- I could walk through a bathtub (v1.1);
- Forward and backward default mapped as 'up' and 'down'. I would expect 'W' and 'S'. (v1.21);
- Sound not working as superuser, but who would use that anyway :) (v1.21);
Tested on Arch Linux.
