I wish you could reply to other people's comments on here. I figured the game was an early project, not beginner at all considering the complexity. There's upgrades, tiers of locked upgrades, maps that unlock those upgrades... etc. Didn't notice a performance hit, and my computer was $500ish from like... 2010? I don't even know. First play in 2022 and I liked it, I just have got to go to sleep for work tomorrow.
Well done dude, hopefully you've made something else in the meantime. I'll have to check when I get home. I'm sure it could've been better, but ~13 years ago? I'm not mad at all, still enjoyable!
