You mixed both of favorite genre and created something amazing!
The gameplay is so engaging and the need to look for fuel instead of sitting at one place and just spam enemies is a great choice. The abilities are great too even though some like the sword don't seem to be worth spending fuel on.
Also I don't know if it's intentional or not but at some point all of a sudden enemies got waaay too fast and I lost.
Awesome game. You need to expand it after the jam!
