Hi @bigeyekitteh! Thank you very much for the review! About the first (major) bug, we think it's been fixed in the new update (you have v-0.1.2 while the current is v-0.1.3. If you play again and see this error again, please let us know! Anyway, we'll dig in case we missed something ;-D
We don't understand what you mean about the second bug, but you surely can destroy objects with the Game Creator tools (not displayed in the demo)! The tools are currently in review. Once they are live, we'll post an update and if you decide to start your own game (go for it! We actually want to do the same!), don't hesitate to ask us any questions! :-D
PS: In case you want to know, the first glitch was caused because of a bug of the game creator tools (now fixed thanks you all the community in itch.io that spotted it) that happened when clicking near an interactable object that moved the player. What happened was that there was a "fight" between the instruction of moving the player to the mouse position and the interaction happening at the same frame.
Cheers!
