Really cool game! The visuals were really cool and I loved the glitch effects! I played the version with icons and they definitely helped a lot. I would also suggest adding some feedback (like an error sound) when you attempt to do something you can't (like trying to collect energy with the corruption) to make it even more clear. Once I got it, the gameplay flowed really nicely! I beat all 6 levels and I think the difficulty was pretty good, but they did feel a little "linear". I don't think this is a bad thing (I definitely struggle with making my games too hard) but I think adding some more mechanics to increase complexity would be helpful if you plan to add more. [Spoilers] Currently, most difficult puzzles revolve around a red herring wrench (level 4 and 6 are essentially the same) and I'm not really sure how you would expand on the puzzles past this without any new mechanics. Level 5 seems difficult at first but your limited movement options mean that for the first 50% of the puzzle there's only one way to go, and once you've done that its pretty clear how to win. As it stands though, the gameplay is really tight and is perfect for the first couple levels. I hope you keep working on it, there's definitely a lot more potential with this concept!
