This game rocks!Keep up the good work!


Thank you for checking it out! I'm glad you enjoyed it~


what really sucks is the recoil from damage.
I mean in the forth or so collidor when you have to fly through the spike mazes one touch of the spikes will kill you. cause you get hit, get knocked to the other side with spikes,  take damage, getting hit back to the start, etc.

basically instadeath if you hit the spike things once.


I wholeheartedly agree! In later updates to the game (post Jam) it was overhauled to be far less punishing. At some point in time I'll upload the ConBravo color version of the game so you can check out the improvements :)

beat the game anyways, that was just something that I didnt like about the game there :-)

What a great retro style game. We enjoyed it very much. The music was great.

Here is a short video we made while playing:

Thank you so much for checking it out! I'm glad you enjoyed it :)

These are the games why I love doing what I'm doing! Holy hell, what a ride!

I'm glad you're enjoying it!

Are you kidding me? This is one of the best games ever!

An Update and Build:



Going to be at ConBravo this month to show off Derelict EX- a more robust, fleshed out, full length version of this game~ If anyone's going to be there, find me in the indie area~

how did it go back then? :-)

you should make a colorful sequel of this game

Was definitely considering it! For now, I'm working on expanding the game to be fully featured with more levels and bosses, as well as polished visuals :) I have some progress shots on my Twitter. A color update may come at some point in time after this iteration goes gold~


I've uploaded the color version of the game that I showed at ConBravo if you want to check it out! https://programancer.itch.io/derelict-ex
It's still unfinished, and due to some strange source corruption I was unable to finish the ending sequence of the game, but- it's the most complete version of Derelict that exists! It has some bugs, no sounds, but the game can be played start to finish *until* the ending sequence. It's way more polished, colorful, and all around a better experience than this version :)

This really reminds me of Layla (Famicom)

Working on fleshing this out and making it a full game~ Next update won't come until that's done!

Okay nevermind, I just beat the bastard. But yeah there's one configuration of those sliding things which seems pretty much impossible to avoid.

Also wanted to edit my previous message but I had to delete it instead because when I went to edit it, the text box would de-select itself after every button input, meaning I'd have to click the box again with my mouse every time I'd press a key, for the entire message. I never had that happen before on any website ever.

Really cool but also really hard! :O

Awesome game!

Can I ask if you can send me the sprite walking cycle?

Me & my friend thought it looked really simple & good and is just what we need! (We wont be using the sprite we will only be looking at your walking cycle and then try and do something similar)


Fun! Wish there were gun/health upgrades. Also wish you could save. Level 3 was very frustrating to invest 10 minutes only to have to start all over at the elevator again if I died.

Those things may be coming in the next update :) I actually already have assets made for gun upgrades and such, just never had a chance to implement them. Had to rush a lot to get it ready for the jam deadline~

A question about the gun - after collecting my first upgrade (from beating the first boss), the gun shortly after reverted back to the base level at some point and I never saw any upgrades again, was that meant to happen?

(1 edit)

Upgrades work like Blaster Master- taking damage removes 1 level of weapon power. There's effectively 2/40 chance to get a drop from an enemy; 1/20 for health, 1/20 for weapon upgrades, so there's a chance you won't see an upgrade unless you're killing a bunch of robots.
