The movement really adds to this entry I think, because without it it would just be a twin stick shooter. To make this easier for the player to understand, maybe having a grid or a tile system on the floor could help? Kinda like chess?

Overall pretty fun and quick to finish <3

Nice job! This is pretty fun :3

A little bug-report: for some reason, the sprites of the bullets and the pick-ups of bullets don't appear on the linux build (they appear as the chess-board pattern). It may be related to linux file names being case-sensitive. So checking the names of the files and how you call them in the code to make sure they are exactly the same should fix it.

This was surprisingly very good fun. Surprising because I wouldn't have guessed that the restricted movement would have made an enjoyable game mechanic. But I love that part of it. Excellent work. I think this is your first DragonRuby game, so extra congratulations for that.
