Ehhh... I thin my time wa 16.28? At least 16
I'm still a bit flashed. The idea is certainly great! Did I miss a tutorial? It took me a while to figure out what to do.
The level is quite short, but I really like the approach. I would maybe stop the time when you switch to time mode. That gives the player a chance to realise what is actually happening and turns the game a bit more into a puzzle game, still including action elemets as the player will have to switch mode before anything happens!
I think players rarely got a chance to react to anything currently, most will either know whats coming and plan ahead or simply fail. That is why I would prefer the puzzle approach. Additionally the pause would allow to make more complex "riddles" where the player actually has to think. Especially if you add more variables like directions or other stuff.
Hard to say much more. The low poly graphic is fine. You probably know that you miss both a floor texture and music, sound etc. Ofc UI, Hiscore etc etc etc would all be cool.
It's a bone, a nice bone tho! Like it :)
