Woah, that's a lot of feedback.
"it could've used some motion while walking to give it more depth", yeah I was planning on adding view bobbing and camera shake but I had to cut it off my list because I was literally working on other more necessary things till the last second.
"different colors, enemies etc.", that was my original plan, to have different themed levels, but as I was adding the base mechanics I realized there was no way I was gonna have time to.
"the game is way too long", sorry about that XD but it was intentional, since I'd finished all the base mechanics with 3 hours left and left all the level making till the end, I just spent the remaining time making levels and figured it wouldn't hurt to add a bunch, just more gameplay time if someone wanted to, but wow! You played it for an hour, that needs some pretty hard dedication. I myself have only made it to level 10 lol. But the last level is level 20 (named level 00) which I pretty much made impossible to beat with a 50 x 50 maze and 4 robot spawners, but to make it easier I added 2 exits on all the levels after level 11 I think, I don't even remember it was like 4am for me I'd stayed up all night. But yeah I went overboard with the levels for maybe that one person that dedicates super hard to it and somehow beats it all, but you're free to go as far as you want.
"hard on the eyes after awhile and it can be pretty disorienting when you're looking around quickly", you're very right about I thought it wouldn't matter in the beginning since I wanted to add different themes, but since that didn't happen, I dunno I just kept it, couldn't find anything that fits as well as it did.
"has a lot of potential with a few adjustments", yeah, big idea, not enough time, which is why I'm considering continuing the game, I had a long list of things I still wanted to add, like different themes/enemies, different maze shapes, moving walls, flags to mark where you've been, and general visual improvements.
Thanks for all the feedback, I really love me some good constructive criticism.
