Hey man I fee your anger, had something similar happen to my game in an early stage. Make sure to check your bin on your desktop. I straight up deleted all my sprites one time.
Anyways I played your game and it had very fun mechanics and beautiful art! do wish you wil pick this one up again eve after the anger hahaha. The graphics are what I liked most about the game together with the soundeffects. Even if this version is old it handles pretty well and looks finished. You shouldnt feel so bad about this project, it very much still has tons of potential to be a fun game to people out there!
Please make sure to take a look at my game if you have some time spare! Our gaems aren't similar, but perhaps we could still learn from each other!
