Thanks for the feedback and playing the game! I understand what you mean about the non-puzzle elements. My aim was to create as many interesting levels as possible without recycling too many puzzle ideas from other levels, so I thought adding the sentries would give me more material to design with overall. Making them easier may have been a remedy to the problem but I felt like it wouldn't have been a challenge if that were the case.
When it came to those time challenges and levels that you need to lose before realising what you have to do, I think I straight up made the mistake of thinking annoying the player in that kind of way was good game design.
The various issues came from it being unfinished. If you read the games main page you'll see instructions that were not explained properly in the game. Thanks for the feedback though, I definitely found a lot of those functional issues after submitting it and playing it myself (overlooked them while testing for some reason). If you continue playing you'll also see how it fits into the theme.
