Super addictive game! Popping space bugs feel so satisfying and it reminds me of Starship Trooper which you definitely cant go wrong.1 found this helpful
Was gonna play for 10 minutes and ended up hooked on it for over 100! I missed my lunch! The Hook is great. The Vibe is great. Will definitely play it to completion!1 found this helpful
Dev is super awesome and generous. He tossed some keys my way for a community giveaway. All in all, I'd of paid for the game. It's not your typical node busting incremental. it gives you real choice each time you prestige on how you wanna build it out for the next prestige. Rockets? Exploding machine guns? Bombing runs? The world is your oyster. I did get the game for free, but I'd of gladly paid for it. I do wish there was more content, but am still not upset. I will say my demo progress carried over, so if you've played the demo, you may want to delete your save and start fresh. It's worth it.1 found this helpful
The gameplay is fun, the art style is cool, and the upgrades are interesting. While it does have a couple minor bugs and might benefit from some additional polish, it works well, and it's very enjoyable. It's also an amazing achievement from an effectively single person indie game developer, and it's easily worth the price. If this is one of PolyB Games' first entries into indie games, I can't wait to see the next!
The "1 billion bugs" achievement takes hours and hours to get. This game is more slop. The magic word on Steam is "incremental" and this trash is what we'll keep getting. Avoid.
Buggy game from the start. When starting a new game, it would freeze during the intro. Reinstalled and clicked continue and it let me skip the intro. Not sure what I missed. Repurchasing upgrade tree between each level is really annoying and time consuming. Repetitive gameplay that is not that rewarding. Some of the achievements are grindy especially with low replayability. Currently not worth the price or the frustration. I did not refund, but I wish I did.
