This feels like Tower of god the game, only going down instead of up! Honestly very good bases here, could definitely use a better progression as it feels too grindy at the start, especially for a game jam game (i ended up playing for an hour lol, that says a lot of good about the game too). I think with some more progression, maybe money multipliers to make it exponential or something, and maybe faster to clear floors, you could still keep the 100 floors which i think is pretty cool as a concept. It was very fun to play nonetheless, so great job and thanks for building this!
Btw what engine did you use for this? Or is it something custom?
