I sadly wasn't able to beat this one, I think I made it to the final boss but I just couldn't finish it off.
There was some very solid "so bad its good" stuff in this though, which is impressive for a first video game! And props for implementing multiple endings, I frankly gave up on trying to implement those in jams years ago because I found almost no one went to the effort of replaying.
The gameplay itself was kinda interesting, it was neat seeing another game with a dodge roll mechanics. Though frankly I wish I could roll up and down rather than just horizontally.
The healing by standing still worked for me, but it was hard to tell at first. My recommendation would be to have the player hold down Q and have some little whirring sound and small visual effect play. As it is I wasn't convinced pressing Q did anything the first couple tries.
I sadly didn't reach an ending, but this was a solid SBIG entry, good work!
