Awesome game for this console with very smooth scrolling and varied weaponry. We are very excited about the finished version. Our German-language preview can be found in our recorded livestream starting at 05:19:50. English subtitles are also available. Subscription to our YouTube and Twitch channel is welcome. 🙂
The game is great, a nice addition to the SMS library
I absolutely love this game !!!!!!
Very cool! I really enjoyed playing this, looking forward to seeing the rest of the game progress. And if you end up doing a physical release, I'll buy it!
Hey there, I hope you don't mind, but I popped gameplay footage of your game into my latest
August 2025 "new games for retro platforms" video. Many thanks for the game.
awesome! looks like an 8-bit soilder series game! hope you are thinking of a physical sms cart down the road! count me in!
Really impressed by this demo. You've got programming for the SMS figured out, that's for sure
Really Amazing Long Live the SMS
This is so awesome!
Honoring the Master System 🫡
Really nice job! Love the graphics, sound, and game play. My favorite genre of game. You really brought the SMS to life… again!
Cool!
:)
Loved the graphics, the colors, the fonts. Finished the demo and the difficulty is honest, good bullet patterns. The soundtrack has 2 insteresting tunes for me. The "Transparency" in the Warning text before the Boss is very cool ;)
if possible, tell your sound designer to create an FM version of the soundtrack :D
Congratulations, the game looks great. What engine was it made in?
Thanks! It's my own engine (collisions, behaviour, effects etc), but with a lot of low level and tooling help from devkitSMS: https://github.com/sverx/devkitSMS
What beautiful colors and graphics. The Master System seems to have more capabilities than the NES, but Nintendo, with its exclusive contracts, blocked many Master System games that would certainly be more beautiful and have better graphics. I appreciate your effort, initiative, and dedication to the Master System, and I hope you can finish it. Congratulations!
man please, youtube channel
I do have a channel but don't post there yet. I'll try to create more videos there. https://www.youtube.com/@badcomputer0
