Hi Oggal! I played this one through to completion. Very cool! I just want to say, your puzzles were very well designed. I would be eager to play a full, polished game of puzzles like this or progressively harder. They actually made me stop and think about sequence, so nice job on the rewind theme as well!
I had some issues with mechanics. Namely, the E button to pick up the cube was buggy and inconsistent. I was able to make it work, but in the very first level I had trouble figuring out how to advance just because the rewind did nothing and picking the cube up kept dropping it immediately. No worries, I got it eventually. I'm not a huge fan of the rewind meter in the middle of the screen; for one, in sections where I need to do a long rewind (near the end of the last level), it just felt clunky to have to stop a few times during the process. Secondly, it's small, faint and hard to see (on my screen, at least). Lastly, some subtitles would help the dialogue. My sound was on but a bit low, and so I missed instruction on level 1.
Despite the critique, I really did enjoy this game and the level design especially. Very nice work on this one, now go have some cake!
