This game is really well done (art, music, tutorial), fits the theme, but is not fun. There is something wrong about controls and design, i'm sure you ran out of time (submitted "18 seconds before the deadline"). One level only or procedural level design is a better choice for a jam.

We didn't get the fundamentals working until very late so had no time to add juice or do balance. But I'm sure you'll be happy to know that after many tweaks the new as-yet-unreleased build is much juicier.
This was also our first time working with the Tile Editor so we've learned a lot of lessons that will greatly speed out dev time for the next jam!
