I like this unique take on Space Invaders-like games. It did confuse me at first but it clicked with me when I learned that your HP is your timer and discovered the permanent upgrades. I think it's satisfying to upgrade your gun through spending gold in the skill tree, letting you destroy as many rocks as possible to get even more gold. To top it all off, the sprite work for the characters and UI is good as well, if not a bit simplistic.

I do have a few issues, though, like the lack of a background sprite and, no music and a couple of grammatical errors. Also I could tell you probably wanted to add more upgrades but didn't have the time because there was a trail in the skill tree that led to nothing. Maybe a different end screen upon collecting all upgrades would've been cute, too.

Overall, though, good job!

If you like, you can try out my game.

Really nice incremental take on this kind of game!

I had a lot of fun seeing how you handled the progression tree and upgrade balance, especially because I wrestled with very similar problems in my own game and ended up solving them in a pretty different way.

Definitely gave me a few ideas to take away from it. Great job!

The start is slow and a little frustrating, but after a few upgrades, it speeds up insanely. Good job, it just needs some balancing tweaks!

the upgrade system feels kinda annoying cuz of the timer in the beginning, but then it escalates and it doesn't become an issue. Great job! also love the unique gameplay and the "bullet explode" thing

Very addictive upgrade system you have here. Great game!

This was a lot of fun! I like that the upgrades make a real tangible difference to gameplay - the progression feels great

This is fun and well made. There a lot of little details that makes the game have a great feel.

The main gameplay mechanic is interesting and have a (small) learning curve 

It's definitively missing more content -- I want to keep playing  :PP

Incredibly underrated! I love incremental games so. hehe

I had fun playing this. It gets insanely easy pretty quickly but it was a nice change of pace from digging games. Good job!

Love this. Starts out kinda skillful and quickly ramps up to just pure insanity  once you get some of the upgrades going. I like the interfaces and the way we move around the systems. Very satisfying to play from beginning to end. Good SFX as well. 

I love these kinds of dopamine-fueled games, and this one feels really good to play. The more you progress, the more hooked you get. The game feel is really good :)

Really fun. I maxed all the upgrades. Thanks for giving the controls some wiggle room when buying stuff. There’s a lot of games here where it’s too easy to accidentally press A and quit out from a shop or something. Very very good interface in general. Also not too hard or too easy.
