Really nice game! I included it in my Nokia 3310 Jam 4 compilation video series, if you’d like to take a look. :)

To future players: when in the boss room, if you die, make sure to jump or press right key to avoid the dying glitch. I'll update after the game jam concludes 

The coins will do stuff in the future updates. Thanks for playing! I'll look into why the boss room kills you like that.

Played till the end. 1st level was really difficult but the others were easier. Nice clean graphics especially love the torches. Ran into a few bugs, on the dragon I died by touching him but hen I respawned the shoot button damages me on subsequent respawns, fixed by jumping. Any reason to collect the coins?
