There I found a way of removing the issue. Sorry again for that, but at least it won't be an issue for future customers. Send me your email with a proof it's you at admin@aeonstarinteractive.com and I'll send a little something your way as a compensation.
I aboslutely loved playing this game, good challenge, I had to slow down the emulator to fight the bosses, unfortunately I didn't put my anxiety to peak level when going through boss battles. I know there were patterns to fight them, but again, UH UH. Thank you for the game, hopefully you make a sequel or prequel to the game. Thanks again!
We're working on the next NES game in parallel to our PC game (Feoderatus). It's not going to be a prequel or sequel to Steel Legion, but it's very much in the same "type": a tight metroidvania with a high but fair difficulty in combat. Next one will have some RPG elements! We'll keep it secret a bit for now since it's second priority, but I'm sure you'll like it.
