Great platforming game! It reminds me of the N64 era of games where you collect stuff. I'm impressed with how polished this game is with the amount of time for the jam. It almost feels like a commercial game.
Something to note: I had to retry Vaitus 2 times to figure out where I was supposed to go (I was stuck at 6 fuels). The reason why is because I thought the buttons spawned an alien after you pressed E rather than using one of your own alien as weight to open the gates. "1 more button to push" is vague and pressing the E option showed up to grab the alien (basically I assumed you press E twice to get an alien).
There's an issue with the collision because I was able to jump through a bunch of walls and ground. I think you should reduce/remove the intensity of the sun and make it bright after the time is up. I was able to collect 10 fuels but I lost my way back to the ship because the screen was way too bright. It's stressful enough being under a time limit. I think you should combine every objective in the planet so there's only one selection. Why? Because if I'm able to collect 15 fuel during my 10 fuel run, then why should I waste my time replaying the same level? You can switch to a star system like in Angry Birds. 10 fuels = 1 star, 15 fuels = 2 stars, 20 fuels = 3 stars.
Overall, great game! It's no surprise you guys were the champions of the previous jam.
