What Steam players say

Recent verbatim reviews from Steam — separate from playze.io community reviews below.

✦ AI summary

ESA SHIELD is praised by players as a creative and interesting concept with educational potential about the Copernicus program, but criticized for being too short, lacking depth in content and mission design, and suffering from unclear UI and unclear launch mechanics that frustrate gameplay. Players see promise in expanding it as an idle game with more automation and slower progression, though several note it currently feels like a proof of concept rather than a complete experience, and suggest trying it since it's free while the developers consider adding more content and detail.

What the, did you make this so short so you could present a playthrough within 15 minutes to your profs with their terrible attention span? I mean I get respecting your players time but you could have paced this a little slower. with a bit more rudimentary mission design, and no hard win / fail condition within the first few minutes. I love this and with a few tweaks and rebalancing this could be suuuuuuuch a great idle game / education game. Play around with automosation more, and make stuff take longer to unlock. Came into this hoping I could also interactively learn something about the copernicus program. If you make this a good idler people would reasonably buy this between 3-5€ surely you wont have to pay esa roalyties either I mean """we""" already financed them from public money so its more or less public domain anyways.

Is it a good game? Kind of. Is it replayable? No. Is it lacking in content? Yes... A Decent game, it's okay for like thirty minutes. Give it a try, it's free. Maybe they'll add more stuff.

Fun game, but there is much more that could be added and I would suggest more detail into research, and popular support from the public. Depending on what the Dev's are aiming for, they could go many different ways with this game. I loved playing, and cant wait to see more depth and detail in this proof of concept.
Not recommended Sep 7, 2025
Awful UI. The game briefly shows you how to defend against asteroids, but when I tried to build a rocket, the menu to actually launch it into orbit didn’t work at all. I had more than enough science to launch, clicked the asteroid, clicked around the static picture of the planet, tried dragging and dropping something—nothing. Meanwhile, the countdown kept ticking. Just lame.
