That was a really fun game to play! I had to restart a few times to get the hang of thing but after the first few rough starts this really played quite well. The idea of going back multiple times to where you started is a fun take on start at the end.
I really liked the building setup you had there, it really felt like there is a lot that could be added to it, like traps of different kinds and what not - like a cold snap that would be a single use block that turns to a wood block after or something, this would give drive to not just have a single straight line to allow multiple enemies to get hit by aoe.
Note to anyone who is streaming playing these games, this game takes up a lot of cpu, so make sure you are on gpu render on obs!
Great work!
