Hey :D First of all, great effort in finishing in the time you did. It's fun to play, and I especially like the bow mechanic. you've really executed that well. I'd be tempted to remove his two attacks at the start so you have to find the bow to be able to beat the orcs. Definitely needs more enemies, but I see this is a prototype for another project so I'm guessing that's just something you don't really need to implement/test in this version, but I think it'd make it more fun with archer orcs, or maybe wizard orcs would be better, firing firebolts and stuff ;)
Graphics are great, love the pixel art, and the music is spot on, and also love how you've implemented the sound FX. It's not easy coordinating all that with jumping, attacking etc etc
It's super cool how you've done the treasure chests - it's quite satisfying Mario-ing them into a reward :D
My only real criticism is the jumps. They feel unnatural, he goes way too high too quickly (IMHO of course) and it does seem that it's the one thing you haven't spent as much time on - I totally get that, I made a platformer before in the last camp and my jumps need quite a bit of work to sort out - not sure if you had the same experience, but it is a real rabbit hole - in mine I had ledges, which were basically triggers, which then boosted the jump, and that took ages and I still haven't really got it down properly. So I'm not saying your jumps are bad, they're good, but they just make it way too easy to complete. I think it comes with the sparse level design. Like, if you were making this as a game, I think you'd need to pad out the levels, improve the platforms and work out more precise jumps and sort places where the player may land, and possible hazards around the spots where he'll end up.
I'm just thinking out loud, no expert or anything, and you've obviously done a great job with this, but if you were looking for areas to improve, those would be my suggestions ;)
But, yeah, amazing effort in the time - you produced a fun and readable 2D pixel art platformer in a very quick time, and it's really cool how you've been updating it cos you got the prototype done so quickly - I should take a few tips haha :D
Great work, man, look forward to seeing how it progresses!
