EXO-Roid is a free NES-style action-adventure. Drop onto a hostile planet with nothing but a beam pistol, find the gear hidden in its depths, defeat the guardians, and record your testament at the shrines before the planet claims you.

Then make your own planet — a full level designer is built in, and every map you publish lands on the community list for everyone to play and vote on.

⚙ EXPLORE. UPGRADE. RETURN.

One connected planet per map — locked routes open as you grow stronger, in classic Metroidvania style.
14 upgrades to hunt down — the Void Marble, High Jump Spring, Ice Beam, Time Ray, Nano Node, Speed Booster, Double Jump, hazard suits and more. Each one reshapes how you move through the world.
5 guardians stand between you and the planet's core — defeating them physically reshapes the map.
Testament Shrines — record your testament at a shrine to save your journey. No autosave. Reaching the shrine is the challenge.
10 zones — rusted metal decks, ice caverns, toxic bogs, the airless surface, the corruption, and worse.

✎ DESIGN YOUR OWN PLANET

Paint rooms with the real in-game art — what you see in the editor is what players get.
Place enemies, bosses, items, secret passages, boss-gated blocks and mysterious Z-link doors.
Test-play instantly from any room, with any loadout.
Submit to the community in one click — players vote your map up the list.
(The designer needs a keyboard and mouse — build on desktop, play anywhere.)

🕹 CONTROLS

Keyboard: Arrows move · Z jump · X fire · Shift switch weapon · Down = Void Marble · C = Nano · Up = doors, shrines & warps

Gamepad supported — plug in a controller and the prompts adapt.

was a nice game, could use more checkpoints! ;-)

oh and please upp the spawn rate for rockets a bit!
I found the one path to the surface where you can kind of grind them.
but befire that I seriously thoguht I was stuck since rockets sicne to only be totten by thos super rare rockets bundles that you find in the world.

only later after desperately searching for rockets and finding thatI suddenly had more rockets I realized that they DO indeed drop. just very rarely so if you dont pay attention you will never relaize it. and think like me initially that rockets are rarely found finite items.anyways ebat the game in short of 70 minutes (69:57).sadly only got 51 of 58 items(88%).

kinda sad that respawning on the testaments kind of resets your progress on blocks destryoyed by rockets or ball bombing.you gotta do them anew.while you only get a fresh 15 rockets.
that aside, good game. map would be nice.

Hey! Thanks for playing and thanks for the feedback! yeah I probably know where the rockets spawn so i didn't find them a problem. I just usually farm the enemies for them as well.

Im considering doing away with the password save system and just have the save state to record all the brick destruction.

You can also create your own maps in the designer. thats how I put together the map you played. I hoping people will make some awesome maps for the community map section I can then place in the main map section.
