Hey! This is definitely one of the best games i played in this jam!
i was amazed that you went for procedural generation in such a short amount of time. It took me a couple of minutes to figure out the controls but after that everything clicked. The controls were just fine. The jump initially felt long but i realized after playing that is useful to be that way for climbing purposes. Actually placing stuff down to climb up was a bit hard so i mostly used the miner to break the ground and make steps for me to go up.
I managed to finish the game .. almost :P I managed to craft the parts i needed but the game crashed on me while i was trying to build my escape pod. It was not really clear what i had to do there as my first thought was i need to install those parts in the broken spaceship but this didnt work, so i thought maybe i need to build a new one.
I got the Boss, i crafted the MK2 miner which was very useful, the ultimate weapon and armor only the scientists have haha. From a design perceptive my advice would be to limit the how deep the player can fall down so it is easier to climb up, or even try to make the placing stuff a bit better so that you can jump and place things below you like you would do in Minecraft. i also noticed that crafting an item gave me x2 or x3 the item i clicked on so there could be an improvement too.
Honestly, one of the best games games i played so far that kept me enganged till the end! More people need to play this for sure!
Good job and keep it up! You got a nice base for a game here!
