The only thing I'll complain about is in 19, you have to get the dynamite on the box, then push both over to the pit. I would just lower the platform on which the dynamite sits on.
The portals look the same color, sry I'm color blind. You should use colors with high contrast between them ex: one set be read and the next yellow.
Other than that it was a great game overall
I love this game but plz tactisoft bring back the old fuel system, I'm running out of lvls and fuel is my wait in this. Honesty I grind the final boss for 3 min. (how long it takes to run out of fuel) then boost, Finally I hit the arena and wait for my fuel to recharge
ok have to admit it is complicated at first but, after you figure out how to craft it gets really easy! (PS the further you go in campaign the better items you can grind) A sure 3-4.5 for me!

After pushing the bomb on top of the box you can push the box out of the way.
