It’s a shame the game is so short. You can cheese the enemy AI a bit by just standing right around a corner :) that way you don’t take any damage and can get through the level with full health ;)
I think it would have been cool to include weapon impact sounds and make the background music a bit more subtle in comparison. A bit more sprite variety could also have added some visual diversity. On the other hand, the Wolfenstein 3D vibe comes across really well!
Great jam entry overall ;) just a pity that it’s so short.
