Clever game. You need to balance how amount you drill, you need to stop to take some aliens down and repair your machinery. Graphs are simple but yet beautiful, game is 5/5 for fun and humor. Nice entry.

Sweet Game! I would love to hear a pitch modulation on the drilling sound.

Liked it! You can make levels and even boss and different drills to expand on this! Loved the graphics and gameplay!

I like this. It's simple, but it does encourage you to sit inside that turtle drill even while the aliens are coming down the walls, which adds quite a bit of tension. It helps that it's hard to know exactly how many hits it'll take to kill one. I feel as though the controls could be simplified a bit, though. Maybe just the down key to get into the drill and upgrade your weapon (since it's otherwise unused and you can't do both at once)?

Fun little game, it's the first game I've rated that I actually got to the end before I felt like I understood everything about it. The screen shake started to give me a bit of a headache though.

Great game, need to have different sounds of each upgrade when you are shooting

Fun game. Main game loop was good. I liked how the upgrade box was not there first but it parachuted down when you had some money.

Wow, the aliens wouldn't stop coming, but I loved the 8 bit feel.

Cute little game. I really enjoyed the artstyle and the music and the gameplay is smooth and fun and I think adding some more challenge and a some better progression would make the game even cooler. Great entry and good job!

I like how this game tries to overwhelm you with more and more enemies, but manages to not feel completely unfair. Instead of relying on RNG, you just have to make quick decisions on how you are going to spend your time. Very clever entry.

Smart gameloop! I enjoyed having the keep a balance between upgrades, shooting and collecting.
My recommendation would be to define better the need for the grill, I did not felt a lot of difference from been inside it to just waiting for the minerals to pop up.

I got the $100! wahoo I'm rich!!

The length of the game and the overall balance was good.

All the suggestions that come to mind are all game-feel polish related stuff: It'd be nice if being in the drill felt ...better somehow. Like, maybe it could drill faster with the ores could be further apart to balance it. And maybe there's some other action you can do in the drill. I also felt the drilling sound effect was a little jarring, not too bad though.

For the visuals, it could be cool if there was more color variety as you dug down into the different layers.

But yeah overall, a nice clean game!
