Hi thank you for playing!
I initially had mouse controls set up, but I temporarily disabled it cause I was getting annoyed by using an ability when I just tried to click somewhere in editor, then in my sleepiness towards the end of the jam I forgot to re-enable it again :') I'll make sure to bring it back in the post jam update! Sorry for that! There ARE a bunch of alternative controls available as mentioned on the page :D (Usually we'd have rebinds too, but scope for the jam went a big too far and we didn't have time anymore D:)
The boss isn't broken, for jam reasons, this being a Ludum Dare entry, (we do want to motivate players to reach the end of the game) instead of giving the player any sort of game-over, the time just turns back a little. Not sure if we'll get to implement a proper game-over / life restoring system post-jam though, sadly!
Thank you for the little review, it's always nice to hear what people think! :D
