How could i unlock the two last characters?

Just wanted to say I absolutely adore this game's soundtrack. Much respect and appreciation to Gyrowolf! I've already bought it on Steam, since that seems to be the only option currently... is there any chance of it being released on Bandcamp, or added to streaming services like Tidal or Spotify? Maybe a YouTube playlist? Thank you for any information you may have about this....

what s engine of this game (if any)?

I tried it on 2 computers. Both with Windows 10 and a good nvidia card. The Logo of the company shows up, but after that it shut down. Any ideas?
