Best game I played so far.
Gameplay:
It's marvelous, juicy and fun. Imo these engineers are a bit oversensitive, but that just makes this game more challanging. There should be some kind to intro about how to avoid explosing, as it took my a while on level one to understand how to be sensitive. So much respect that you even added a boss fight that is interesting.
Graphics:
Game is so well juiced. Starting with simplistic, but fun artstyle, a lot of gream transitions. Cool ragdols that sometimes tear heads of other engineers. You made great use of effects like shakes, particles, transitions and because of that it all feels as the whole. Great job!
Audio:
What a great melody you made. It fits game perfectly getting my attention all the time. I really felt like I was the guy launching the pad. Sounds are also great.
Innovation:
It kinda reminds me of Tomorrow Corporation games like "Human Resource Machine" (I love these games), so I love what you did. Idea with sticky and explosive people is just great and it leaves a lot of room for extending that, eg. with portals. Intro is so great that I'm fairly impressed.
Theme:
Leaps reference is really nicely done. I also got bounds idea, so it fits theme great.
Overall, what a game. I just wish you could make up plot to it and mix it with some levels so that there is a feel like you are going somewhere beating those levels (as beginning is really interesting). I love you xD
