Alright, so I think I found the top 3 contender for sure!!!! God dammit this was SOOOO good, like I would play this over and over again if it had more enemies and level variations and powerUp variations (maybe like some small ammo pack to kill those pesky enemies on the red levels).
Such a great idea and done so well and the whole concept of building your own level and based on that trying to quickly go through everything to kill the opponent, once again SOOOO GOOOD!
Found one issue, one of the maps (the enemy places on that I can't look at what that room is) like you can see all the others and what the "challenge"/level will be, but that won't give you the popup info. It has those to lines almost from top to bottom and bottom to top on the other side.
Also missed completely that if you get hit you lose time, maybe it was said there, but I normally like to just jump into the game and see if it is intuitive and easy to learn, but that I just realised maybe on the second or third round when I was wondering why my time was so low :D
