I played the game for almost 20 minutes(i know this is a very short time) and here's my opnion:
(Note: I'm not good at reviewing games)
1. The game have a complex control system
It's not really complex, but like, W and UP Arrow and Space Bar are yes good for jumping, idk how to explain what i want to say, but i got confused that the Space Bar is the only jumping method that doesn't waste fuel and it's unnoticeable this mechanic. Also i almost forgot to use Sprinting, but this is just me being noob
2. Is that level possible to beat?
I got stucked at Level 4(i don't remember if it was Level 4). The level is like:
2 Fuel rechargers on the beggining and you need to go up.
There's on part that i can't go up, there's no fuel recharger next to me, it's impossible!
I know that i played the game for a very short time and i'm not so good at game reviewing, i give this gane 5.5/10
