What Steam players say

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

✦ AI summary

Robosynthesis is a charming, bite-sized platformer with cute aesthetics and fun gameplay that players can complete in under an hour. Most reviewers praise its engaging design and achievement of 100% completion in a single sitting, though the game is notably very short, and some report a bug where revived players lose jump functionality and experience low gravity issues. Players generally feel it's a worthwhile free-to-play experience, though a few suggest the concept could work well expanded into a paid release.

An absolutely cute game that stars an absolutely cute robot girl. I got all achievements in one sitting, and what a wonderful one sitting it was, enjoyed it from start to finish! More action games with cute robot girls please! An extra point for having a mega buster too!

Bite sized fun.

cute, fun and short, definitely could see the concept expanded into a paid game. Very nice. also, the complains about the controls probably refer to gamepad, I had a lovely time with the kb+mouse.

fun little gem

It's a decent platformer. Can't really complain if it's free to play. I took an hour to finish it 100 % and since it's an achievement to complete the game in under 10 minutes you might already guess how long it is.

Games like Portal 2 all share one habit: teach a single impossible trick, then spend a campaign breaking it. From rewinding objects through time to Escher geometry that loops back on itself.

Planet Coaster DLC: skip the collection, buy the packs

The Planet Coaster DLC catalogue closed in 2019, so there is no curve left to wait out. Our record shows the collection bundle costs far more than assembling the same packs one by one.
